DESCRIPTION

The

M54HC251

is

an

high

speed

CMOS

8-CHANNEL

MULTIPLEXER

(3-STATE)

fabricated with silicon gate C2MOS technology.

This Multiplexer features both true (Y) and

complement (W) outputs as well as STROBE

input. When the STROBE is high, both outputs are

in the high impedance state. When enabled,

address information on the data select inputs

determines which data input is routed to Y and W.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
