1 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.
2 See Figure 4 for maximum rated current values for various temperatures.
3 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.

Description
Normal operation; data is high.
Normal operation; data is low.
Input unpowered. Outputs are in the default high state.
Outputs return to input state within 1 μs of VDDI power restoration.
See the pin function descriptions (Table 19 through Table 21) for more
details.
Output unpowered. Output pins are in high impedance state.
Outputs return to input state within 1 μs of VDDO power restoration.
See the pin function descriptions (Table 19 through Table 21) for more
details.
1 VIx and VOx refer to the input and output signals of a given channel (A, B, C, or D).
2 VDDI refers to the power supply on the input side of a given channel (A, B, C, or D).
3 VDDO refers to the power supply on the output side of a given channel (A, B, C, or D).
