54ACT323

8-Bit Universal Shift/Storage Register with Synchronous

Reset and Common I/O Pins

n Common parallel I/O for reduced pin count

General Description

n Additional serial inputs and outputs for expansion

The ’ACT323 is an 8-bit universal shift/storage register with

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

TRI-STATE^®outputs. Parallel load inputs and flip-flop out-

store

puts are multiplexed to minimize pin count. Separate serial

inputs and outputs are provided for Q₀and Q₇to allow easy

cascading. Four operation modes are possible: hold (store),

n TRI-STATE outputs for bus-oriented applications

n Outputs source/sink 24 mA

n TTL-compatible inputs

shift left, shift right and parallel load.

n Standard Military Drawing (SMD)

— ’ACT323: 5962-91607

Features

n I_CCand I_OZreduced by 50%
