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”.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.

are protected from damage due to static discharge by inter-
nal diode clamps to V
