NOTES:

H = High voltage level

L = Low voltage level

h = High voltage level one set-up time prior to the High-to-Low LCXX transition

l = Low voltage level one set-up time prior to the High-to-Low LCXX transition

X = Don’t care

Z = High-impedance (OFF) state

— = Input not externally driven

↑ = Low-to-High transition

↓ = High-to-Low transition

H** = Goes to level of pull-up voltage

Bn* = 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.
