Truth Table
1. The data output functions may be enabled or disabled by various signals at the xOEAB or xOEBA inputs. Data
2. Select control = L: clocks can occur simultaneously.

Function/Operation
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.
Select control = H: clocks must be staggered in order to load both registers.
H = High Voltage Level; L = Low Voltage Level; X = Don’t Care;
