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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
The internal circuit is composed of 3 stages
including buffer output, which provides high noise
immunity and stable output.
