*Pb-free PDIPs can be used for through hole wave solder processing

only. They are not intended for use in Reflow solder processing.

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.

θJA 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.
