DESCRIPTION
The 74LVX20 is a low voltage CMOS DUAL
4-INPUT NAND GATE fabricated with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.
The internal circuit is composed of 3 stages
including buffer output, which provides 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
system. It combines high speed performance with
the true CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
