Isolation Group
The device is considered a 2-terminal device: Pin 1 through Pin 8 are shorted together and Pin 9 through Pin 16 are shorted together.
Input capacitance is from any input data pin to ground.
In accordance with UL 1577, each ADuM744x is proof tested by applying an insulation test voltage ≥1200 V rms for 1 sec (current leakage detection limit = 5 µA).
