DESCRIPTION
The 74ACT257 is an advanced high-speed CMOS
QUAD 2-CHANNEL MULTIPLEXER (3-STATE)
fabricated with sub-micron silicon gate and
double-layer metal wiring C
It is composed of an independent 2-channel
multiplexer with common SELECT and ENABLE
(OE)inputs. It is a non-inverting multiplexer. When
the ENABLE input is held HIGH, the outputs are
forced to a high impedance state. When the

SELECT input is held LOW, "A" data is selected;
when SELECT input is held HIGH, "B" data is
selected.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
