¹The device is considered a 2-terminal device: Pin 1 through Pin 4 are shorted together, and Pin 5 through Pin 8 are shorted together.

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

REGULATORY INFORMATION

The ADuM7240/ADuM7241 are pending approval 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.

Table 14.

UL (Pending)

Recognized Under UL 1577 Component Recognition Program¹

Single Protection, 1000 V rms Isolation Voltage

File E274400

¹In accordance with UL 1577, each ADuM7240/ADuM7241 is proof tested by applying an insulation test voltage ≥1200 V rms for 1 sec (current leakage detection limit = 5 µA).
