DESCRIPTION

The M74HC21 is an high speed CMOS DUAL

4-INPUT AND GATE fabricated with silicon gate

C MOS technology.

All inputs are equipped with protection circuits

against static discharge and transient excess

voltage.

The internal circuit is composed of 3 stages

including buffer output, which enables high noise

immunity and stable output.
