74HC51 Overview
The M74HC51 is an high speed CMOS DUAL 2 WIDE 2 INPUT AND/OR INVERT GATE fabricated with silicon gate C2MOS technology. It contains a 2-WIDE 2-INPUT AND/OR INVERT GATE and a 2-WIDE 3-INPUT AND/OR INVERT GATE. The internal circuit is posed of 3 stages (2 INPUT) or 5 stages (3 INPUT) including buffer output, which enables high noise immunity and stable output.
