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.

AC ELECTRICAL CHARACTERISTICS (Input tr=tf=3ns)

CAPACITIVE CHARACTERISTICS

1) CPDis defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without
load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. I
