Description
The 74LCX00 device is a low-voltage CMOS
quad dual input NAND gate manufactured with
sub-micron silicon gate and double layer metal
wiring C 2MOS technology. It is ideal for low-power
and high-speed 3.3 V applications and can be
interfaced to a 5 V signal environment for inputs.
It has the same speed performance at 3.3 V as
the 5 V AC/ACT family, combined with lower
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2 kV ESD immunity and transient excess
voltage.

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 Section 5: Test circuit). Average operating current
can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/4 (per gate).
