Stresses at or above those listed under Absolute Maximum Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability.

VDDI and VDDO refer to the supply voltages on the input and output sides of a given channel, respectively. See the PC Board Layout section. 5
See Figure 4 for maximum rated current values for various temperatures. 6
This refers to common-mode transients across the insulation barrier. Common-mode transients exceeding the Absolute Maximum Ratings may cause latch-up or permanent damage.

VIx and VOx refer to the input and output signals of a given channel (A, B, C, or D). VEx refers to the output enable signal on the same side as the VOx outputs. VDDI and VDDO refer to the supply voltages on the input and output sides of the given channel, respectively. 2
In noisy environments, connecting VEx to an external logic high or low is recommended.
