DESCRIPTION

The 74LVX27 is a low voltage CMOS TRIPLE

3-INPUT NOR GATE fabricated with sub-micron

silicon gate and double-layer metal wiring C2MOS

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.
