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.

Input voltages may exceed the supply voltages provided the input current is limited to ±100 μ A.
Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
Refer to “Differential Input” discussion.
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.
5: The TC7116/TC7116A logic inputs have an internal pull-down resistor connected from HLDR, Pin 1 to TEST, Pin 37. The
TC7117/TC7117A logic inputs have an internal pull-down resistor connected from HLDR, Pin 1 to GND, Pin 21.
