General Description
The V HC04 i s an adv anced hi gh speed C MOS Inv erter
fabricated with silicon gate CMOS technology. It achieves
the hi gh sp eed op eration si milar to e quivalent B ipolar
Schottky TTL while maintaining the CMOS low power dissi-
pation.
The internal circuit is composed of 3 stages including buffer
output, which provide high noise immunity and stable out-
put. An input protection circuit ensures that 0V to 7V can be
applied to the input pins without regard to the supply volt-
age. This device can be used to interface 5V to 3V systems
and two supply systems such as battery back up. This cir-
cuit prevents device destruction due to mismatched supply
and input voltages.
