74AC153 74ACT153
Dual 4-Input Multiplexer
General Description
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 gener-
ate any two functions of three variables.
