CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
5. 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 and ICL7660A.
6.
JA
is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief
TB379
for details.
7. For
JC
, the “case temp” location is taken at the package top center.
8. Pb-free PDIPs can be used for through-hole wave solder processing only. They are not intended for use in reflow solder processing applications.

Electrical Specifications
ICL7660S and ICL7660A, V+ = 5V, T
A
= +25°C, OSC = Free running (see Figure 12, “ICL7660S Test Circuit”
on page 7 and Figure 13 “ICL7660A Test Circuit” on page 7), unless otherwise specified.
9. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified. Temperature limits established by characterization
and are not production tested.
10. In the test circuit, there is no external capacitor applied to pin 7. However, when the device is plugged into a test socket, there is usually a very
small but finite stray capacitance present, on the order of 5pF.
11. The Intersil ICL7660S and ICL7660A can operate without an external diode over the full temperature and voltage range. This device will function
in existing designs that incorporate an external diode with no degradation in overall circuit performance.
12. All significant improvements over the industry standard ICL7660 are highlighted.
13. Derate linearly above 50°C by 5.5mW/°C.
