The M54/74HC20 is a high speed CMOS DUAL 4-

INPUT NAND GATE fabricated in silicon gate

C

formance of LSTTL combined with true CMOS low

power consumption.

The internal circuit is composed of 3 stages includ-

ing buffered output, which gives high noise immunity

and a stable output. All inputs are equipped with pro-

tection circuits against static discharge and transient

excess voltage.
