74HC21D Overview
General The 74HC21D is a high speed CMOS 4-INPUT AND GATE fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The internal circuit is posed of 4 stages including buffer an output, which provide high noise immunity and stable output.
74HC21D Key Features
