M54HCT02 - QUAD 2-INPUT NOR GATE
The M54/74HCT02 is a high speed CMOS QUAD 2-INPUT NOR GATE fabricated in silicon gate C2MOS technology.
It has the same high speed performance of LSTTL combined with true CMOS low power consumption.
The internal circuit is composed of 3 stages including buffer output, which gives high noise immunity
