General Description

The NC7SU04 is a singl e special pu rpose CMOS Inverter.
The inverter circuit is designed with a single unbuffered
stage to facilitate use in crystal oscillator applications. It is
not intended for use in logic inversion applications.

Advanced Silicon Gate CMOS fabrication assures high
speed and low pow er circuit operation over a broad V

range. ESD protecti on diodes inherently guard both input
and output with respect to the V

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, with­out exception, to ensure that the system design is reliable over its power
supply, temperature, and ou tput/inp ut loadi ng varia bles. Fairchild does no t
recommend operat ion of circuits outside databook specific at ions.

Note 2: Unused inputs must be held HIGH or LOW. They may not float.
