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.

1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/4(per circuit)
