54AC153 • 54ACT153
Dual 4-Input Multiplexer
General Description
Features
n ICC reduced by 50%
The ’AC/’ACT153 is a high-speed dual 4-input multiplexer
with common select inputs and individual enable inputs for
each section. It can select two lines of data from four
sources. The two buffered outputs present data in the true
(non-inverted) form. In addition to multiplexer operation, the
’AC/’ACT153 can act as a function generator and generate
any two functions of three variables.
n Outputs source/sink 24 mA
n ’ACT153 has TTL-compatible inputs
