Hex Inverter
General Description
The VHC04 is an advanced high speed CMOS Inverter
fabricated with silicon gate CMOS technology. It achieves
the high speed operation similar to equivalent Bipolar
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.
