DESCRIPTION
The M74HC51 is an high speed CMOS DUAL 2
WIDE
2
INPUT
AND/OR
fabricated with silicon gate C
2
MOS technology.
It contains a 2-WIDE 2-INPUT AND/OR INVERT
GATE
and a 2-WIDE 3-INPUT
INVERT GATE.
INVERT
GATE
AND/OR
The internal circuit is composed of 3 stages (2
INPUT) or 5 stages (3 INPUT) including buffer
output, which enables high noise immunity and
stable output.
All inputs are equipped with protection circuits
against static discharge and transient excess
voltage.
