Quad 2-Input NOR Gate
The TC74HC02A is a high speed CMOS 2-INPUT NOR GATE
fabricated with silicon gate C
2
MOS technology.
It achieves the high speed operation similar to equivalent
LSTTL while maintaining the CMOS low power dissipation.
The internal circuit is composed of 3 stages, including a buffer
output, which provide high noise immunity and stable output.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
