1 All voltages are relative to their respective ground.
2 VDDI and VDDO refer to the supply voltages on the input and output sides of
a given channel, respectively.
3 See Figure 3 for information about maximum allowable current for various
temperatures.
4 Refers to common-mode transients across the insulation barrier. Common-
mode transients exceeding the Absolute Maximum Rating can 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.
