DESCRIPTION

The 74VHCT05A is an advanced high-speed

CMOS OPEN DRAIN HEX INVERTER fabricated

with sub-micron silicon gate and double-layer

metal wiring C2MOS technology.

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.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
