The data output function may be enabled or disabled by various signals at the OEBA and OEAB 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 clock.
If both Select controls (SAB and SBA) are Low, then clocks can occur simultaneously. If either Select control is High, the clocks must be
staggered in order to load both registers.

The select pins determine whether data is stored or transferred
through the device in real time.
The output enable pins determine the direction of the data flow.
