Description

Normal operation, data is high.

Normal operation, data is low.

Input unpowered. Outputs return to input state within 1 μs of VDD1 power restoration.

See the Power-Up/Power-Down Considerations section for more details.

Output unpowered. Output pins are in high impedance state. Outputs return to

input state within 1 μs of VDD2 power restoration. See the Power-Up/Power-Down

Considerations section for more details.

1 VIx and VOx refer to the input and output signals of a given channel (A, B, C, D, or E).
