DESCRIPTION

The M54/74HC4078 is a high speed CMOS 8

INPUT NOR/OR GATE fabricated in silicon gate

C2MOS technology. It has the same high speed

performance of LSTTL combined with true CMOS

low power consumption.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.
