Refers to common-mode transients across the insulation barrier. Common-mode transients exceeding the Absolute Maximum Rating may cause latch-up or perma-

nent damage.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only;

functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions may affect device reliability.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the

human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.

* Pins 2 and 8 are internally connected. Connecting both to GND

is recommended. Pins 9 and 15 are internally connected. Connecting both to GND

Output enable Pin 10 on the ADuM1400 may be left disconnected if outputs are to be always enabled. Output enable Pins 7 and 10 on the ADuM1401/ADuM1402

may be left disconnected if outputs are to be always enabled. In noisy environments, connecting Pin 7 (for ADuM1401 and ADuM1402) and Pin 10 (for all models) to

an external logic high or low is recommended.
