applications.
CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. Connecting any terminal to voltages greater than V+ or less than GND may cause destructive latchup. It is recommended that no inputs from
sources operating from external supplies be applied prior to “power up” of ICL7660S.
2. JA is measured with the component mounted on an evaluation PC board in free air.

NOTE:
3. Pin 1 is a Test pin and is not connected in normal use. When the TEST pin is connected to V+, an internal transmission gate disconnects any
external parasitic capacitance from the oscillator which would otherwise reduce the oscillator frequency from its nominal value.
