2 / 10 page www.fairchildsemi.com 2 Connection Diagram Truth Table (Note 2) H = HIGH Voltage Level L = LOW Voltage Level X = Immaterial = LOW-to-HIGH Clock Transition Note 2: The data output functions may be enabled or disabled by various signals at OEAB or OEBA inputs. Data input functions are always enabled, i.e., data at the bus pins will be stored on every LOW-to-HIGH transition on the clock inputs. This also applies to data I/O (A and B: 8–15) and #2 control pins.
