DESCRIPTION
The 74VHCT05A is an advanced high-speed
CMOS OPEN DRAIN HEX INVERTER fabricated
with sub-micron silicon gate and double-layer
metal wiring C
2
MOS 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 since all inputs are
equipped with TTL threshold.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
