Product Pin Configuration
Notes
:
1.The data output functions may be enabled or disabled by various signals at the xOE or xDIR 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.
2. Select control = L: clocks can occur simultaneously.
Select control = H: clocks must be staggered to load both registers.
H = High Voltage Level; L = Low Voltage Level; X = Don’t Care;
↑
= LOW-to-HIGH transition
