= 48 kHz. TC7116/TC7116A and TC7117/TC7117A are tested in the
circuit of Figure 1.
4. Refer to "Differential Input" discussion.
5. 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 50 mV.
6. 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.
