2 / 6 page www.fairchildsemi.com 2 Function Table H = HIGH Voltage Level X = Immaterial L = LOW Voltage Level = LOW-to-HIGH Transition. Note 1: The data output functions may be enabled or disabled by various signals at the G and DIR inputs. Data input functions are always enabled; i.e., data at the bus pins will be stored on every LOW-to-HIGH transition of the appropriate clock inputs. Also applies to data I/O (A and B: 8-15) and #2 control pins.
