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
s ICC and IOZ reduced by 50%
s Outputs source/sink 24 mA
s ACT157 has TTL-compatible inputs
