• 54ACT251

8-Input Multiplexer with TRI-STATE® Output

General Description

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 vari-

ables. Both true and complementary outputs are provided.

Features

n ICC reduced by 50%

n Multifunctional capability

n On-chip select logic decoding

n Inverting and noninverting TRI-STATE outputs

n Outputs source/sink 24 mA

n ’ACT251 has TTL-compatible inputs

n Standard Military Drawing (SMD)
