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 20 through Table 22) 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 20 through Table 22) 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).
