Quad 2-Input NOR Gate
The TC74HC02A is a high speed CMOS 2-INPUT NOR GATE
fabricated with silicon gate C2MOS 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.
Features
Note: xxxFN (JEDEC SOP) is not available in
Japan.
