DESCRIPTION
The M74HC02 is an high speed CMOS QUAD
2-INPUT NOR GATE fabricated with silicon gate
C
2
MOS 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.
