DESCRIPTION
The M54HC20 is an high speed CMOS DUAL 4-INPUT NAND GATE fabricated with silicon gate C2MOS technology.
The internal circuit is composed of 3-stage including buffered output, which gives high noise immunity and stable output.
All inputs are equipped with protection circuits against static discharge and transient excess voltage.

■ HIGH SPEED: tPD = 9ns (TYP.) at VCC = 6V
■ LOW POWER DISSIPATION: ICC = 1µA(MAX.) at TA=25°C
