*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.

ELECTRICAL CHARACTERISTICS: VS = 9V, fCLK = 16 kHz, and TA = +25°C, unless otherwise noted.

NOTES: 1. Input voltages may exceed supply voltages when input current is limited to 100

µA.

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

µA (typical). Common current not included.
