*Stresses above those listed under "Absolute Maximum
Ratings" may cause permanent damage to the device. These
are stress ratings only and functional operation of the device
at these or any other conditions above those indicated in the
operation sections of the specifications is not implied.
Exposure to Absolute Maximum Rating conditions for
extended periods may affect device reliability.

Note
1:
Input voltages may exceed the supply voltages, provided the input current is limited to ±100
A.
2:
Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
3:
Refer to “Differential Input” discussion.
4:
Backplane drive is in phase with segment drive for “OFF” segment, 180° out of phase for “ON” segment.
Frequency is 20 times conversion rate. Average DC component is less than 50mV.
