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 μ A.
2. θ JA is measured with the component mounted on a low effective thermal conductivity test board in free air. See Tech Brief TB379 for details.

NOTES:
3. Tested in 4 1 / 2 digit (20.000 count) circuit shown in Figure 3. (Clock frequency 120kHz.)
4. Tested with a low dielectric absorption integrating capacitor, the 27 Ω INT OUT resistor shorted, and R lNT = 0. See Component Value Selection Discussion.
5. The temperature range can be extended to +70 o C and beyond as long as the auto-zero and reference capacitors are increased to absorb the higher
leakage 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.
