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