54AC299 • 54ACT299

8-Input Universal Shift/Storage Register with Common

Parallel I/O Pins

n Common parallel I/O for reduced pin count

General Description

n Additional serial inputs and outputs for expansion

The ’AC/’ACT299 is an 8-bit universal shift/storage register

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

with TRI-STATE^®outputs. Four modes of operation are pos-

store

sible: hold (store), shift left, shift right and load data. The par-

allel load inputs and flip-flop outputs are multiplexed to re-

duce the total number of package pins. Additional outputs

n TRI-STATE outputs for bus-oriented applications

n Outputs source/sink 24 mA

n ’ACT299 has TTL-compatible inputs

n Standard Microcircuit Drawing (SMD)

’AC299: 5962-88754

are provided for flip-flops Q₀, Q₇to allow easy serial cascad-

ing. A separate active LOW Master Reset is used to reset the
