CD40106 - Hex Schmitt Trigger Inverter IC The CD40106 IC consists of six Schmitt-Trigger inputs. Each circuit functions as an inverter with Schmitt-Trigger input. The trigger switches at different points for positive- and negative-going signals. The difference between the positive-going voltage (VP) and the negative-going voltage (VN) is defined as hysteresis voltage (VH). A Schmitt trigger input means that the threshold voltage for going from a HIGH to a LOW input is different from the threshold for going from LOW to HIGH.

CD4011 - Quad 2-Input NAND Gate IC The CD4011 is a quad package 2-Input NAND gate IC (Integrated Circuits). That is, it has four NAND gates inside a single package and each gate has two input lines and one output line. All the inputs and outputs are buffered and this improves transfer characteristics by providing a very high gain. The CD4011 IC operates at 5V, 10V, 15V, and even 20V. When operating at 5V the maximum low-level input voltage is 0.5 and the minimum high-level input voltage is 4.5. All four gates share the same power rail but can operate independently.

CD4013 - Dual D Type Flip-Flop IC The CD4013 designed as a CMOS logic chip IC belongs to the CD4XXX IC series. The CD4013 device comprises two identical, independent data-type flip-flops. Each flip-flop comes with independent data, set, reset, and clock inputs, and Q and Q’ outputs. These devices are commonly used for shift register applications, and, by connecting Q output to the data input, for counter and toggle applications. The logic level present at the D input is transmitted to the Q output during the positive-going transition of the clock pulse. Moreover, the Setting or resetting of IC is independent of the clock and accomplished by a high level on the set or reset line, respectively.  The CD4013B is manufactured in 14-pin dual-inline plastic packages (E suffix), 14-pin small-outline packages (M, MT, M96, and NSR suffixes), and 14-pin thin shrink small-outline packages (PW and PWR suffixes). A D-type Latch/flip-flop is designed as a clocked latch that has two stable states. A D-type latch operates with a delay in input by one clock cycle. Thus, by cascading many D-type flip-flops delay circuits are often created, which are utilized in many applications like in digital television systems.  A D-type flip-flop is additionally mentioned as a D flip-flop or a delay flip-flop. The D flip-flop is an edge-triggered device that transfers input files to Q on a clock rising or falling edge. Data Latches are level sensitive devices like the data latch and therefore the transparent latch. Applications Power Delivery Grid Infrastructure Medical, Healthcare, and Fitness Body Electronics and Lighting Building Automation Telecom Infrastructure Test and Measurement

CD4015 - Dual 4-Stage Shift Register IC The CD4015 IC consists of two identical, independent, 4-stage serial-input/parallel-output registers. Each register has independent CLOCK and RESET inputs as well as a single serial DATA input. “Q” outputs are available from each of the four stages on both registers. All register stages are D-type, master-slave flip-flops. The logic level present at the DATA input is transferred into the first register stage and shifted over one stage at each positive-going clock transition. Resetting of all stages is accomplished by a high level on the reset line. Register expansion to 8 stages using one CD4015 package, or to more than 8 stages using additional CD4015’s is possible. The CD4015-series types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic package (E suffix), 16-lead small-outline packages (M, M96, MT, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes). check out : CD4034 - 8-Stage Bidirectional Bus Register IC (Original) Pinout: Pinout Of CD4015 - Dual 4-Stage Shift Register IC Pin Name Pin # Type Description VDD 16 Power Supply Voltage (+3 to +15V) GND 8 Power Ground (0V) D A 7 Input Data pin for register A CLK A 9 Input Clock pulse for register A RST A 6 Input Reset pin for register A Q A0 ,Q A1 ,Q A2 ,Q A3 5,4,3,10 Output 4-bit output for register A D B 15 Input Data pin for register B CLK B 1 Input Clock pulse for register B RST B 14 Input Reset pin for register B Q B0 ,Q B1 ,Q B2 ,Q B3 11,12,13, 2 Output 4-bit output for register B Applications: Serial-input/parallel-output data queueing Serial to parallel data conversion General-purpose register

CD4016 - Quad Bilateral Switch IC The CD4x Series CD4016 is a quad bilateral switch intended for the transmission or multiplexing of analog or digital signals. It is pin-for-pin compatible with CD4066B. The CD4016 is a CMOS IC with four analog switches, which can be controlled individually using a control pin. The signal can flow in either direction between the two pins of each switch. Each switch has an enable pin (A) and two input/output pins (X and Y). When the enable pin is set to HIGH, current can flow between X and Y in either direction. However, when enable is LOW, no current can flow between the pins. Just like a switch.

CD4017 - Decade Counter IC The CD4017 IC is a decade counter that counts to ten. It has 10 outputs that represent the numbers 0 to 9. The counter increases with one for every rising clock pulse. After the counter has reached 9, it starts again from 0 with the next clock pulse. This is a great chip for making running LEDs!

CD4028 - BCD to Decimal Decoder IC CD4028 IC is a BCD to decimal or binary to octal decoder consisting of 4 inputs and 10 output buffers. A BCD code is applied to the 4 inputs, A, B, C, and D. Thus resulting in a high level at the selected 1-of-10 decimal decoded outputs. Similarly, a 3-bit binary code applied to inputs A, B, and C is decoded into octal at outputs 0–7. A high-level signal at the D input inhibits octal decoding and causes outputs 0–7 to go LOW. The IC is always available in a 16–pin hermetically sealed dual inline IC package (DIP), making it easy to interface with TTL, CMOS, and NMOS devices. The IC offers many features such as high noise immunity and low thermal dissipation.  High drive capability is provided at all outputs to enhance dc and dynamic performance in high fan- ut applications. Meanwhile, all the inputs are protected against static discharge damage by diode clamps to V DD and V SS . A BCD to Decimal Decoder is defined as a simple logic circuit that can translate a BCD (binary coded decimal) input into a decimal (0 – 9) output In any BCD to decimal decoder, the inverters are connected in pairs to make BCD input data available for decoding by the NAND gates. Full decoding of valid BCD input logic ensures that all outputs remain OFF for all invalid binary input conditions. Moreover, these decoders feature TTL inputs and high–performance NPN output transistors designed for use as indicator/relay drivers or as open–collector logic circuit drivers. check out : CD4514 - 4 Bit Latch/4-16 Line Decoder IC Pinout: Pinout of CD4028 IC Application Code conversion Address decoding Indicator-tube decoder

CD4029 - Binary Decade Up-Down Counter IC The CD4029 IC consists of a four-stage binary or BCD-decade up/ down counter with provisions for look-ahead carry in both counting modes. The inputs consist of a single CLOCK, CARRY-IN (CLOCK ENABLE), BINARY/DECADE, UP/DOWN, PRESET ENABLE, and four individual JAM signals. Q1, Q2, Q3, Q4, and a CARRY OUT signal are provided as outputs. A high PRESET ENABLE signal allows information on the JAM INPUTS to preset the counter to any state asynchronously with the clock. A low on each JAM line, when the PRESET-ENABLE signal is high, resets the counter to its zero counts. The counter is advanced one count at the positive transition of the clock when the CARRY-IN and PRE-SET ENABLE signals are low. Advancement is inhibited when the CARRY-IN or PRESET ENABLE signals are high. The CARRY-OUT signal is normally high and goes low when the counter reaches its maximum count in the UP mode or the minimum count in the DOWN mode provided the CARRY-IN signal is low. The CARRY-IN signal in the low state can thus be considered a CLOCK ENABLE. The CARRY-IN terminal must be connected to VSS when not in use. Binary counting is accomplished when the BINARY/DECADE input is high; the counter counts in the decade mode when the BINARY/DECADE input is low. The counter counts up when the UP/DOWN input is high, and down when the UP/DOWN input is low. Multiple packages can be connected in either a parallel clocking or a ripple-clocking arrangement as shown in Figure 17. Parallel clocking provides synchronous control and hence faster response from all counting outputs. Ripple-clocking allows for longer clock input rise and fall times. The CD4x Series CD4029 is supplied in these 16-lead outline packages: Braze Seal DIP H4X Frit Seal DIP H1F Ceramic Flatpack H6W. Pinout: Pinout of CD4029 IC
