The data output functions may be 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 of the clock inputs.
When select control is low, clocks can occur simultaneously if allowances are made for propagation delays from A to B (B to A) plus setup and
hold times. When select control is high, clocks must be staggered to load both registers.
