NOTE:
A-to-B data flow is shown; B-to-A flow is similar but uses OEBA, LEBA, and CPBA.
H = High voltage level
h
= High voltage level one set-up time prior to the Enable or Clock transition
L
= Low voltage level
I
= Low voltage level one set-up time prior to the Enable or Clock transition
NC= No Change
X = Don’t care
Z = High Impedance ”off” state
= High-to-Low Enable or Clock transition
