Quad 2-Input NOR Gate
The TC74HCT02A 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.
This device may be used as a level converter for interfacing
TTL or NMOS to High Speed CMOS. The inputs are compatible
with TTL, NMOS and CMOS output voltage levels.
The internal circuit is composed of 3 stages, including buffer
output, which provide high noise immunity and stable output.
All inputs are equipped with protection circuits against static
discharge or transient excess voltage.
Note: xxxFN (JEDEC SOP) is not available in
Japan.
