8-Input Universal Shift/Storage

General Description

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

Features

and I

reduced by 50%

Common parallel I/O for reduced pin count

with TRI-STATE outputs. Four modes of operation are

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

parallel load inputs and flip-flop outputs are multiplexed to

reduce the total number of package pins. Additional outputs

Additional serial inputs and outputs for expansion

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

store

are provided for flip-flops Q , Q to allow easy serial cas-

cading. A separate active LOW Master Reset is used to

reset the register.

TRI-STATE outputs for bus-oriented applications

Outputs source/sink 24 mA

’ACT299 has TTL-compatible inputs
