Input voltages may exceed the supply voltages, provided the input current is limited to ±100µA.
Note 2:
Dissipation rating assumes device is mounted with all leads soldered to the PCB.
Stresses beyond 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 beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

section.
Note 5:
Backplane drive is in phase with segment drive for “off” segment, 180N out of phase for “on” segment. Frequency is 20
times the conversion rate. Average DC component is less than 50mV.
