† The data-output functions are enabled or disabled by a variety of level combinations at OEAB or OEBA. Data-input functions are always enabled;
i.e., data at the bus terminals is stored on every low-to-high transition on the clock inputs.
‡ Select control = L; clocks can occur simultaneously.
Select control = H; clocks must be staggered to load both registers.
