DESCRIPTION
The 74LVX32 is a low voltage CMOS QUAD
2-INPUT OR 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 2 stages
including buffer ou tput, 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 eq uipped with protection circuits
against static discharge, giving them 2KV ESD
immunity and transient excess voltage.
