1. The data output functions may be enabled or disabled by various signals at the xOEAB or xOEBA 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.

3. H = HIGH Voltage Level

L = LOW Voltage Level

X = Don't Care

↑ = LOW-to-HIGH Transition

NOTES:

1. Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-

INGS may cause permanent damage to the device. This is a stress rating

only and functional operation of the device at these or any other conditions

above those indicated in the operational sections of this specification is not

implied. Exposure to absolute maximum rating conditions for extended

periods may affect reliability.
