Common-Mode Transients4
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. See the PC Board Layout section.
3 See Figure 4 for maximum rated current values for various temperatures.
4 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.

1 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.
