DESCRIPTION
The 74LX 1G132 is a low v oltage CMOS SINGLE
2-INPUT NAND GATE fabricated with s ub-micron
silicon gate and double -layer metal wiring C
2
MOS
technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
immunity and stable output.
Power down prot ec tion is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. Th is device can be
usedto interface5V to 3V.
This together with its schmitt t rigger function
allows it to be used on line receivers with slow
rise/fall input signals.
All inputs and outputs are equipped with
protection circuits against static discharge.
