CD4504 - Hex Voltage-Level Shifter IC The CD4504 hex voltage level shifter IC consists of six circuits that shift input signals from the V CC logic level to the V DD logic level. To shift TTL signals to CMOS logic levels, the SELECT input is at the V CC HIGH logic state. When the SELECT input is in a LOW logic state, each circuit translates signals from one CMOS level to another. The CD4504 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, and MT suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

CD4511 - BCD To 7 Segment Latch Decoder Driver IC The CD4511 IC types are BCD-to-7-segment latch decoder drivers constructed with CMOS logic and n-p-n bipolar transistor output devices on a single monolithic structure. These devices combine the low quiescent power dissipation and high noise immunity features of RCA CMOS with n-p-n bipolar output transistors capable of sourcing up to 25 MA. This capability allows the CD4511 types to drive LED's and other displays directly. Lamp Test (LT)\, Blanking (BL)\, and Latch Enable or Strobe inputs are provided to test the display, shut off or intensity-modulated it, and store or strobe a BCD code, respectively. Several different signals may be multiplexed and displayed when external multiplexing circuitry is used. The CD4x Series CD4511 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (NSR suffix), and 16-lead thin shrink small-outline packages (PW and PWR suffixes).

CD4514 - 4 Bit Latch/4-16 Line Decoder IC The CD4x Series CD4514 IC is a 4-to-16-line decoder with latched inputs implemented with complementary MOS (CMOS) circuits constructed with N- and P-channel enhancement mode transistors. These circuits are primarily used in decoding applications where low power dissipation and/or high noise immunity are required. The CD4514 (output active high option) presents a logical “1” at the selected output. The input latches are R–S type flip-flops, which hold the last input data presented prior to the strobe transition from “1” to “0”. This input data is decoded and the corresponding output is activated. An output inhibits line is also available. Pinout: Pinout Of CD4514 IC

CD4518 - Dual BCD Up Counter IC The CD4x Series CD4518 consists of two identical, internally synchronous 4-stage counters. The counter stages are D-type flip-flops having interchangeable CLOCK and ENABLE lines for incrementing on either the positive-going or negative-going transition. For single-unit operation, the ENABLE input is maintained high and the counter advances on each positive-going transition of the CLOCK. The counters are cleared by high levels on their RESET lines. The counter can be cascaded in the ripple mode by connecting Q4 to the enable input of the subsequent counter while the CLOCK input of the latter is held low. The CD4518  types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (E suffix), 16-lead small-outline packages (M, M96, and NSR suffixes), and 16-lead thin shrink small-outline packages (PW and PWR suffixes). check out : CD4059 - Programmable Divide-by-N Counter IC Pinout: Pinout of CD4518 IC Applications: Multistage synchronous counting Multistage ripple counting Frequency dividers

CD4519 - Quad AND/OR Select Gate IC The CD4x Series CD4519 CMOS IC can be configured as 4-bit AND/OR selectors, as quad 2-channel data selectors, or as quad exclusive-NOR gates. This is achieved by setting the control inputs to produce the particular function desired. The single supply voltage of the CD4519 quad IC is 3V to 18V. Pinout: Pinout of CD4519 IC

CD4532 - 8 Bit Priority Encoder IC The CD4x Series CD4532 consists of combinational logic that encodes the highest priority input (D7-D0) to a 3-bit binary code. The eight inputs, D7 through D0, each have an assigned priority; D7 is the highest priority and D0 is the lowest. The priority encoder is inhibited when the chip-enable input E I is low. When E I is high, the binary representation of the highest-priority input appears on output lines Q2-Q0, and the group select line GS is high to indicate that priority inputs are present. The enable-out (E O ) is high when no priority inputs are present. If any one input is high, E O is low and all cascaded lower-order stages are disabled. The CD4532 types are supplied in 16-lead hermetic dual-in-line ceramic packages (F3A suffix), 16-lead dual-in-line plastic packages (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).

CD4538 - Dual Precision Monostable Multivibrator IC The CD4538 IC is a dual, precision monostable multivibrator with independent trigger and reset controls. The device is re-triggerable and resettable, and the control inputs are internally latched. Two trigger inputs are provided to allow either rising or falling edge triggering. The reset inputs are active low and prevent triggering while active. Precise control of output pulse-width has been achieved using linear CMOS techniques. The pulse duration and accuracy are determined by external components RX and CX. The device does not allow the timing capacitor to discharge through the timing pin on power-down conditions. For this reason, no external protection resistor is required in series with the timing pin. Input protection from static discharge is provided on all pins.

CD4543 - BCD to 7 Segment Decoder IC The CD4543 IC is a BCD-to-seven segment latch/decoder/driver IC designed primarily for liquid-crystal display (LCD) applications. It is also capable of driving light-emitting diode (LED), incandescent, gas-discharge, and fluorescent displays. This device is functionally similar and serves as a direct replacement for the CD4056 when pin 7 is connected to VSS. It differs from the CD4056B in that it has a display blanking capability instead of a level-shifting function and requires only one power supply. When the CD4056 is used in the level shifting mode, two power supplies are required. When the CD4543 is used for LCD applications, a square wave must be applied to the PHASE input and the backplane of the LCD device. For LED applications logic 1 is required at the PHASE input for common-cathode devices; logic 0 is required for common-anode devices (see truth table). The CD4543B is supplied in 16-lead dual-in-line plastic packages (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).
