NOTES:
1. The data output functions may be enabled or disabled by various signals at the xOEAB or x
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 clocks 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

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.
2. All device terminals except FCT162XXXT Output and I/O terminals.
