DESCRIPTION
The M74HC257 is an high speed CMOS QUAD 2
CHANNEL MULTIPLEXER (3-STATE) fabricated
with silicon gate C2MOS technology.
This IC is composed of an independent 2-channel
multiplexer with common SELECT and ENABLE
(OE) input.
The M74HC257 is a non-inverting multiplexer.
When the ENABLE input is held "High", outputs of
the IC become in a High-Impedance state. If
SELECT input is held low, "A" data is selected,
when SELECT is high , "B" data is chosen.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
