¹The device is considered a 2-terminal device: Pin 1 through Pin 10 are shorted together, and Pin 11 through Pin 20 are shorted together.

²Input capacitance is from any input data pin to ground.

REGULATORY INFORMATION

The ADuM7640/ADuM7641/ADuM7642/ADuM7643 are approved by the organizations listed in Table 14. See Table 18 and the

Insulation Lifetime section for recommended maximum working voltages for specific cross-isolation waveforms and insulation levels.

Recognized Under UL 1577 Component Recognition Program¹

Single Protection,1000 V rms Isolation Voltage

File E274400

¹In accordance with UL 1577, each ADuM7640/ADuM7641/ADuM7642/ADuM7643 is proof tested by applying an insulation test voltage ≥ 1200 V rms for 1 sec (current

leakage detection limit = 5 µA).
