*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above 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.

NOTES:
1. Input voltages may exceed supply voltages when input current is limited to 100
μ
A.
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 is 20 times
conversion rate. Average DC component is less than 50 mV.
5. See "Typical Operating Circuit".
6. A 48 kHz oscillator increases current by 20
μ
A (typical). Common current not included.
