74HC157 - Quad 2-input multiplexer

The 74HC/HCT157 are high-speed Si-gate CMOS devices
and are pin compatible with low power Schottky TTL
(LSTTL). They are specified in compliance with JEDEC
standard no. 7A.
The 74HC/HCT157 are quad 2-input multiplexers which
select 4 bits of data from two sources under the control of
a common data select input (S). The four outputs present
the selected data in the true (non-inverted) form. The
enable input (E) is active LOW. When E is HIGH, all of the
outputs (1Y to 4Y) are forced LOW regardless of all other
input conditions.
