General Description

The AC/ACT299 is an 8-bit universal shift/storage register with 3-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 are provided for flip-flops Q₀, Q₇ to allow easy serial cascading. A separate active LOW Master Reset is used to reset the register.

Features

I_CC and I_OZ 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
ACT299 has TTL-compatible inputs
