DESCRIPTION
The M74HC253 is an high speed CMOS DUAL 4
CHANNEL MULTIPLEXER fabricated with silicon
gate C²MOS technology.
Each of these data (1C0-1C3, 2C0-2C3) is
selected by the two address inputs A and B.
Separate strobe inputs (1G, 2G) are provided for
each of the two four-line sections. The strobe input

(nG) can be used to inhibit the data output; the
output of M74HC253 is a high impedance while
the strobe input is held high.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
