Quad 2-Input Multiplexer
General Description
The ’AC/’ACT158 is a high-speed quad 2-input multiplexer. It
selects four bits of data from two sources using the common
Select and Enable inputs. The four buffered outputs present
the selected data in the inverted form. The ’AC/’ACT158 can
also be used as a function generator.
