General Description

The ACT323 is an 8-bit universal shift/storage register with 3-STATE outputs. 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

■ ICC and IOZ reduced by 50

■ Common parallel I/O for reduced pin count

■ Additional serial inputs and outputs for expansion

■ Four operating modes: shift left, shift right, load and store

■ 3-STATE outputs for bus-oriented applications

■ Outputs source/sink 24 mA

■ TTL-compatible inputs
