4-Line to 16-Line Decoder/Demultiplexer IC - 74HC154 This is the 74HC Series 74HC154 IC, Each of these 4-line-to-16-line decoders IC utilizes TTL circuitry to decode four binary-coded inputs into one of sixteen mutually exclusive outputs when both the strobe inputs, G1 and G2, are LOW. The demultiplexing function is performed by using the 4 input lines to address the output line, passing data from one of the strobe inputs with the other strobe input LOW. When either strobe input is HIGH, all outputs are HIGH. These demultiplexers are ideally suited for implementing high-performance memory decoders. All inputs are buffered and input clamping diodes are provided to minimize transmission-line effects and thereby simplify system design.  check out : 74238 IC Pinout: Pinout Of 74HC154 IC Package Includes: Selected qty of IC - 74HC154 Specifications: Supply Voltage (VCC) 7 V Input Voltage (VI) 7 V Operating free-air temperature range 0°C to +70°C  Storage temperature range –65°C to +150°C

Presettable synchronous BCD decade counter IC - 74HC160 The 74HC Series 74HC160 is a high-speed Si-gate CMOS device and is pin-compatible with low-power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC160 are synchronous presettable decade counters which feature an internal look-ahead carry and can be used for high-speed counting. Synchronous operation is provided by having all flip-flops clocked simultaneously on the positive-going edge of the clock (CP). The outputs (Q0 to Q3) of the counters may be preset to a HIGH or LOW level. A LOW level at the parallel enable input (PE) disables the counting action and causes the data at the data inputs (D0 to D3) to be loaded into the counter on the positive-going edge of the clock (providing that the set-up and hold time requirements for PE are met). Preset takes place regardless of the levels at count enable inputs (CEP and CET). A LOW level at the master reset input (MR) sets all four outputs of the flip-flops (Q0 to Q3) to LOW level regardless of the levels at CP, PE, CET, and CEP inputs (thus providing an asynchronous clear function). The look-ahead carry simplifies the serial cascading of the counters. Both counts enable inputs (CEP and CET) must be HIGH to count. The CET input is fed forward to enable the terminal count output (TC). The TC output thus enabled will produce a HIGH output pulse of a duration approximately equal to a HIGH-level output of Q0. This pulse can be used to enable the next cascaded stage.  Pinout: Pinout Of 74HC160 IC Symbol  Pin  Description MR   1 Asynchronous master reset (active LOW) CP   2 Clock input (LOW-to-HIGH, edge triggered) D0, D1, D2, D3   3, 4, 5, 6 Data input CEP 7 Count enable input GND   8 Ground (0 V) PE  9 Parallel enable input (active LOW) CET  10 Count enable carry input Q0, Q1, Q2, Q3  14, 13, 12, 11 Flip-flop output TC  15 Terminal count output VCC   16 Supply Voltage Applications: Television sets Home-sound sets Multimedia systems All mains-fed audio systems Car Audio (boosters).

8-Bit Serial In/Parallel Out Shift Register IC - 74HC164 The 74HC Series 74HC164 IC utilizes advanced silicon-gate CMOS technology. It has high noise immunity and low consumption of standard CMOS integrated circuits. It also offers speeds comparable to low-power Schottky devices. This 8-bit shift register has gated serial inputs and CLEAR. Each register bit is a D-type master/slave flip-flop. Inputs A & B permit complete control over the incoming data. A LOW at either or both inputs inhibits the entry of new data and resets the first flip-flop to the low level at the next clock pulse. A high level of one input enables the other input which will then determine the state of the first flip-flop. Data at the serial inputs may be changed while the clock is HIGH or LOW, but only information meeting the setup and hold time requirements will be entered. Data is serially shifted in and out of the 8-bit register during the positive-going transition of the clock pulse. Clear is independent of the clock and accomplished by a low level at the CLEAR input. The 74HC logic family is functionally as well as pin-out compatible with the standard 74LS logic family. All inputs are protected from damage due to static discharge by internal diode clamps to VCC and the ground.  Pinout: Pinout of 74HC164 IC Pin no.
