8-Input Multiplexer with TRI-STATE Output

General Description

Features

reduced by 50%

The ’AC/’ACT251 is a high-speed 8-input digital multiplexer.

It provides, in one package, the ability to select one bit of

data from up to eight sources. It can be used as universal

function generator to generate any logic function of four

variables. Both true and complementary outputs are provid-

ed.

Multifunctional capability

On-chip select logic decoding

Inverting and noninverting TRI-STATE outputs

Outputs source/sink 24 mA

’ACT251 has TTL-compatible inputs

Standard Military Drawing (SMD)
