Description
The CA3161E is a monolithic integrated circuit that performs
the BCD to seven segment decoding function and features
constant current segment drivers. When used with the
CA3162E A/D Converter the CA3161E provides a complete
digital readout system with a minimum number of external
parts.

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. This is the maximum output voltage for any single output. The output voltage must be consistent with the maximum dissipation and derating curve
for worst case conditions. Example: All segments “ON”, 100% duty cycle.
2. JA is measured with the component mounted on an evaluation PC board in free air.
