NOTE: 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. Input voltages may exceed the supply voltages provided the input current is limited to +100

µA.

NOTES:

4. Tested with a low dielectric absorption integrating capacitor, the 27

Ω INT OUT resistor shorted, and R

of the ICL7135.

6. This specification relates to the clock frequency range over which the lCL7135 will correctly perform its various functions See “Max Clock Frequency”

section for limitations on the clock frequency range in a system.

7. Parameter guaranteed by design or characterization. Not production tested.
