Hex Inverter
General Description
The VHC/VHCT04 is an advanced high speed CMOS IN-
VERTER fabricated with silicon gate CMOS technology. It
achieves the high speed operation similar to equivalent Bi-
polar Schottky TTL while maintaining the CMOS low power
dissipation.
The internal circuit is composed of 3 stages including buffer
output, which provide high noise immunity and stable output.
An input protection circuit ensures that 0V–7V can be ap-
plied to the input pins without regard to the supply voltage.
This device can be used to interface 5V to 3V systems and
two supply systems such as battery back up. This circuit pre-
vents device destruction due to mismatched supply and in-
put voltages.

Note 1:
Absolute Maximum Ratings are values beyond which the device
may be damaged or have its useful life impaired. The databook specifications
should be met, without exception, to ensure that the system design is reliable
over its power supply, temperature, and output/input loading variables. Fair-
child does not recommend operation outside databook specifications.
