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 ±100µA.
2. θ is measured with the component mounted on an evaluation PC board in free air.

NOTES:
3. Unless otherwise noted, specifications apply to both the ICL7116 and ICL7117. ICL7116 is tested in the circuit of Figure 1. ICL7117 is
tested in the circuit of Figure 2.
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 con-
version rate. Average DC component is less than 50mV.
5. Not tested, guaranteed by design.
