Test Conditions
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 the conversion rate. Average DC component is less than 50 mV.
