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.
