*Stresses above those listed under "Absolute Maximum

Ratings" may cause permanent 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

operation sections of the specifications is not implied.

Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability.

TC7106/A AND TC7107/A ELECTRICAL SPECIFICATIONS

Electrical Characteristics: Unless otherwise noted, specifications apply to both the TC7106/A and TC7107/A at TA = 25°C,

fCLOCK = 48kHz. Parts are tested in the circuit of the Typical Operating Circuit.

Note 1: Input voltages may exceed the supply voltages, provided the input current is limited to ±100µA.

2: Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.

3: Refer to “Differential Input” discussion.

4: Backplane drive is in phase with segment drive for “OFF” segment, 180° out of phase for “ON” segment.

Frequency is 20 times conversion rate. Average DC component is less than 50mV.
