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

All voltages are relative to their respective ground.
V DDI and V DDO refer to the supply voltages on the input and output sides of a
given channel, respectively. See the PC Board Layout section.
See Figure 4 for maximum rated current values for various temperatures.
Refers to common-mode transients across the insulation barrier. Common-
mode transients exceeding the Absolute Maximum Rating can cause latch-
up or permanent damage.

V Ix and V Ox refer to the input and output signals of a given channel (A, B, C, or D). V Ex refers to the output enable signal on the same side as the V Ox outputs. V DDI and
V DDO refer to the supply voltages on the input and output sides of the given channel, respectively.
