PIN AND FUNCTION COMPATIBLE

WITH 54/74LS21

The M54/74HC21 is a high speed CMOS DUAL 4-

INPUT AND GATE fabricated in silicon gate C

2MOS

technology. It has the same high speed perform-

ance of LSTTL combined with true CMOS low power

consumption.

The internal circuits is composed of 3 stages includ-

ing buffered output, which gives high noise immunity

and a stable output.

All inputs are equipped with protection circuits

against static discharge and transient excess volt-

age.
