8-Input Multiplexer
General Description
The AC/ACT151 is a high-speed 8-input digital multiplexer.
It provides, in one package, the ability to select one line of
data from up to eight sources. The AC/ACT151 can be
used as a universal function generator to generate any
logic function of four variables. Both true and complemen-
tary outputs are provided.
Features
s ICC reduced by 50%
s Outputs source/sink 24 mA
s ACT151 has TTL-compatible inputs
