The M54/74HC08 is a high speedCMOS QUAD2INPUTANDGATEfabricated insilicongateC2MOS
technology. It has the same high speed performanceofLSTTLcombinedwithtrueCMOSlowpower
consumption.
The internal circuit is composedof 2 stages including buffer output, which gives high noise immunity
and stable output.
All inputs are equipped with protection circuits
against static discharge and transient excess voltage.
