DESCRIPTION
PIN CONNECTIONS (top view)
The M54/74HC21 is a high speed CMOS DUAL 4-
INPUTAND GATEfabricated in silicongate C2MOS
technology. It has the same high speed perform-
ance of LSTTL combinedwithtrue CMOSlowpower
consumption.
The internal circuits is composed of 3 stages includ-
ing bufferedoutput, which gives highnoise immunity
and a stable output.
All inputs are equipped with protection circuits
against static discharge and transient excess volt-
age.
