54AC151 • 54ACT151
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 func-
tion of four variables. Both true and complementary outputs
are provided.
Features
n ICC reduced by 50%
n Outputs source/sink 24 mA
n ’ACT151 has TTL-compatible inputs
n Standard Microcircuit Drawing (SMD)
— ’AC151: 5962-87691
