High voltage level
Low voltage level
High voltage level one set-up time prior to the High-to-Low LCXX transition
Low voltage level one set-up time prior to the High-to-Low LCXX transition
Don’t care
High-impedance (OFF) state
Input not externally driven
Low-to-High transition
High-to-Low transition
Goes to level of pull-up voltage
Precaution should be taken to ensure B inputs do not float. If they do, they are equal to Low state.

NOTE:
In Loopback mode (Loopback = High), AIn inputs are routed to the AOn outputs. The Bn inputs are blocked out.
