*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.

Note

Connecting any input terminal to voltages greater than V+ or less than GND may cause destructive latch-up. It is recommended that no

inputs from sources operating from external supplies be applied prior to "power up" of the TC962.
