MM74HC157
Quad 2-Input Multiplexer
General Description
The MM74HC157 high speed Quad 2-to-1 Line data selec-
tor/Multiplexers utilizes advanced silicon-gate CMOS tech-
nology. It possesses the high noise immunity and low
power consumption of standard CMOS integrated circuits,
as well as the ability to drive 10 LS-TTL loads.
This device consists of four 2-input digital multiplexers with
common select and STROBE inputs. When the STROBE
input is at logical “0” the four outputs assume the values as
selected from the inputs. When the STROBE input is at a
logical “1” the outputs assume logical “0”.
The 74HC logic family is functionally as well as pin-out
compatible with the standard 74LS logic family. All inputs
are protected from damage due to static discharge by inter-
nal diode clamps to V
CC
and ground.
