74VHCU04
Hex Inverter
General Description
The VHCU04 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 dissipation.
Since the internal circuit is composed of a single stage
inverter, it can be used in analog applications such as crystal oscillators. An input protection circuit ensures that 0V to
7V can be applied to t he input pins without r egard to the
supply voltage. This dev ice can be used to interf ace 5V to
3V systems and two supply systems such as battery
backup. Thi s ci r c ui t pr ev ent s d e vi ce d est r uc ti o n du e to m is matched supply and input voltages.

Absolute Maximum Ratings(Note 1) Recommended Operating
Conditions
(Note 2)
Note 1: Absolute Maximum Ratings are values beyond which the device
may be damaged or ha ve its useful li fe impaire d. The datab ook specifications should be met, without exception, to ensure that the system design is
reliable over its p ower supp ly, temperature, and ou tput/input loading variables. Fairchild does not recom mend operation outs ide databook specifications.
Note 2: Unused inputs must be held HIGH or LOW. They may not float.
