74F323

Octal Universal Shift/Storage Register

with Synchronous Reset and Common I/O Pins

General Description

The 74F323 is an 8-bit universal shift/storage register with

3-STATE outputs. Its function is similar to the 74F299 with

the exception of Synchronous Reset. Parallel load inputs

and flip-flop outputs are multiplexed to minimize pin count.

Separate serial inputs and outputs are provided for Q0 and

Q7 to allow easy cascading. Four operation modes are

possible: hold (store), shift left, shift right and parallel load.

Features

s Common parallel I/O for reduced pin count

s Additional serial inputs and outputs for expansion

s Four operating modes: shift left, shift right, load and

store

s 3-STATE outputs for bus-oriented applications
