ProductPinDescription
Notes:
1. H = High Voltage Level, X = Dont Care,
L = Low Voltage Level, ↑= LOW-to-HIGH Transition
* The data output functions may be enabled or disabled by a varietyof level combinations at the OEAB or OEBA
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.
** Select control = L; clocks can occur simultaneously. Select control = H; to load both registers,
clocks must be staggered.
