Input voltages may exceed supply voltages when input current is limited to 100 μ A.
Dissipation rating assumes device is mounted with all leads soldered to PC board.
Refer to "Differential Input" discussion.
Backplane drive is in phase with segment drive for "OFF" segment and 180° out-of-phase for "ON" segment. Frequency
is 20 times conversion rate. Average DC component is less than 50mV.
5: See "Typical Application".
6: A 48kHz oscillator increases current by 20 μ A (typical). Common current not included.
