*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. Unless otherwise noted, specifications apply to the ICL7136 at T A = 25°C, f CLOCK = 48kHz. ICL7136 is tested in the circuit of Figure 1.
4. Back plane drive is in phase with segment drive for “off“ segment, 180 degrees out of phase for “on“ segment. Frequency is 20 times conversion rate.
Average DC component is less than 50mV.
5. Not tested, guaranteed by design.
6. 48kHz oscillator increases current by 20 μ A (Typ).
