2: Dissipation rating assumes device is mounted with all leads soldered to PC board.
3: Refer to "Differential Input" discussion.
4: Backplane drive is in phase with segment drive for "OFF" segment and 180° out-of-phase for "ON" segment. Frequency
5: See "Typical Application".
6: A 48kHz oscillator increases current by 20μA (typical). Common current not included.
