8-Input Multiplexer with 3-STATE Output

General Description

Features

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 pro-

vided.

■ I_CCreduced by 50%

■ Multifunctional capability

■ On-chip select logic decoding

■ Inverting and noninverting 3-STATE outputs

■ Outputs source/sink 24 mA

■ ACT251 has TTL-compatible inputs
