DESCRIPTION
The M54HC257 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.
