2. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
3. Unless otherwise noted, specifications apply to both the TC7106/A and TC7107/A at T
4. Refer to “Differential Input” discussion.
5. Backplane drive is in phase with segment drive for “OFF” segment, 180 out of phase for “ON” segment. Frequency is 20 times
