Description
The M54/74HC21 is a high speed CMOS DUAL 4-INPUTANDGATEfabricated in silicon gate C2 MOS technology. It has the same high speed performance of LSTTL combined with true CMOS low power consumption. The internal circuits is composed of 3 stages including buffered output, which gives high noise immunity and a stable output. All inputs are equipped with protection circuits against static discharge and transient excess voltage.
