DESCRIPTION
The M74HC21 is an high speed CMOS DUAL
4-INPUT AND GATE fabricated with silicon gate
C2MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which enables high noise
immunity and stable output.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
