MM74HC157 Quad 2-Input Multiplexer
General Description
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
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 funct...
