DESCRIPTION
The 74LX1G00 is a low voltage CMOS SINGLE
2-INPUT NAND GATE fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
immunity and stable output.

Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface 5V to 3V.
All inputs and outputs are equipped with
protection circuits against static discharge.

1) CPD is 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. ICC(opr) = CPD x VCC x fIN + ICC
