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.

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.
