Note 1: 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.
