DESCRIPTION

The 74VHC05 is an advanced high-speed CMOS

OPEN DRAIN HEX INVERTER fabricated with

sub-micron silicon gate and double-layer metal

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.
