High Speed CMOS Logic 8-Input Multiplexer with 3-State Outputs

The CD74HC253 and CD74HCT253 are dual 4-to-1 line selector/multiplexers having three-state outputs. One of four sources for each section is selected by the common select inputs, S0 and S1. When the output enable (1OE\, 2OE\) is HIGH, the output is in the high-impedance state. The CD74HC253 and CD74HCT253 are dual... Read More

The ’HC257 and ’HCT257 are quad 2-input multiplexers which select four bits of data from two sources under the control of a common Select Input (S). The Output Enable input (OE\) is active LOW. When OE\ is HIGH, all of the outputs (1Y-4Y) are in the high impedance state regardless... Read More

High Speed CMOS Logic 8-Bit Addressable Latch

This device contains three independent 3-input NOR gates. Each gate performs the Boolean function Y =A + B + Cin positive logic. This device contains three independent 3-input NOR gates. Each gate performs the Boolean function Y =A + B + Cin positive logic.

High Speed CMOS Logic Octal D-Type Flip-Flops with Reset

The ’HC280 and ’HCT280 are 9-bit odd/even parity, generator checker devices. Both even and odd parity outputs are available for checking or generating parity for words up to nine bits long. Even parity is indicated (E output to any input of an additional HC/HCT280 parity checker. The ’HC280 and ’HCT280... Read More

High Speed CMOS Logic 4-Bit Binary Full Adder with Fast Carry

The ’HC297 and CD74HCT297 are high-speed silicon gate CMOS devices that are pin-compatible with low power Schottky TTL (LSTTL). These devices are designed to provide a simple, cost-effective solution to high-accuracy, digital, phase-locked-loop applications. They contain all the necessary circuits, with the exception of the divide-by-N counter, to build first-order... Read More

The ’HC259 and ’HCT299 are 8-bit shift/storage registers with three-state bus interface capability. The register has four synchronous-operating modes controlled by the two select inputs as shown in the mode select (S0, S1) table. The mode select, the serial data (DS0, DS7) and the parallel data (I/O0– I/O7) respond only... Read More

This device contains one independent 8-input NAND gate. Each gate performs the Boolean function Y =A ● B ● C ● D ● E ● F ● G ● Hin positive logic. This device contains one independent 8-input NAND gate. Each gate performs the Boolean function Y =A ● B... Read More

This device contains four independent 2-input OR gates. Each gate performs the Boolean function Y = A + B in positive logic. This device contains four independent 2-input OR gates. Each gate performs the Boolean function Y = A + B in positive logic.

The CD54HC354, CD74HC354, and CD74HCT354 are data selectors/multiplexers that select one of eight sources. In both types, the data select bits S0, S1 and S2 are stored in transparent latches that are enabled by a low latch enable input, LE\. In the HC/HCT354 the data enable input, E\, controls transparent... Read More
