54AC157 • 54ACT157
Quad 2-Input Multiplexer
General Description
The ’AC/’ACT157 is a high-speed quad 2-input multiplexer.
Four bits of data from two sources can be selected using the
common Select and Enable inputs. The four outputs present
the selected data in the true (noninverted) form. The ’AC/
’ACT157 can also be used as a function generator.
Features
n ICC and IOZ reduced by 50%
n Outputs source/sink 24 mA
n ’ACT157 has TTL-compatible inputs
n Standard Microcircuit Drawing (SMD)
— ’AC157: 5962-89539
— ’ACT157: 5962-89688
