X = Don’t care

H = High voltage level

L = Low voltage level

↑ = Low to High

Z = High impedance “off ” state

† = A-to-B data flow is shown: B-to-A flow is similar but uses

OEBA, LEBA, CPBA, and CEBA.

were established.

§ = Output level before the indicated steady-state input conditions

were established, provided that CPAB was Low before LEAB

went Low.
