The MM74HC157 high speed Quad 2-to-1 Line data selector/Multiplexers utilizes advanced silicon-gate CMOS technology. It possesses the high noise immunity and low
power consumption of standard CMO S 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 STROB E inputs. When the STROBE
input is at logical “0” the four outputs assume the values as
selected from the inputs. W hen 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 internal diode clamps to V
and ground.
