2 / 7 page www.fairchildsemi.com 2 Connection Diagram Pin Descriptions Function Table (Note 2) H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial (HIGH or LOW, inputs may not float) Z = HIGH Impedance Note 2: A-to-B data flow is shown; B-to-A flow is similar but uses OEBA, LEBA, CLKBA, and CLKENBA. Note 3: Output level before the indicated steady-state input conditions were established Note 4: Output level before the indicated steady-state input conditions were established, provided that CLKAB was HIGH before LEAB went LOW.
