DESCRIPTION
The 74VHC05 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.
