All voltages are relative to their respective grounds.

VDD1 is the power supply for the push-pull transformer.

VDDI and VDDO refer to the supply voltages on the input and output sides of a

given channel, respectively. See the Printed Circuit Board (PCB) Layout section.

See Figure 3 for maximum rated current values for various temperatures.

Refers to common-mode transients across the insulation barrier. Common-

mode transients exceeding the absolute maximum ratings may cause latch-up

or permanent 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 indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.
