DESCRIPTION
The 74VHCU04 is an advanced high-speed
CMOS HEX INVERTER fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
As the internal circuit is composed of a single
stage inverter, it can be used in analog
applications such as crystal oscillator.
Power down protection is provided on all inputs
and outputs 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.
