DESCRIPTION
The 74LVQ00 is a low voltage CMOS QUAD
2-INPUT NAND GATE fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology. It is ideal for low power and low noise
3.3V applications.
The internal circuit is composed of 3 stages
including buffer output, which enables high noise
immunity and stable output.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
