DESCRIPTION

The 74LCX257 is a low voltage CMOS QUAD 2

CHANNEL MULTIPLEXER (3-STATE) fabricated

with sub-micron silicon gate and double-layer

metal wiring C2MOS technology. It is ideal for low

power and high speed 3.3V applications; it can be

interfaced to 5V signal environment for both inputs

and outputs.

It is composed of four independent 2 channel

multiplexers with common SELECT and ENABLE

(OE) INPUT. The 74LCX257 is a non-inverting

multiplexer. When the ENABLE INPUT is held

"High", all outputs become in high impedance

state. If SELECT INPUT is held "Low", "A" data is

selected, when SELECT INPUT is "High", "B" data

is chosen.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
