2. Data inputs are registered at K and /K rising edges. Data outputs are delivered at C and /C rising edges,
except if C and /C are high, then data outputs are delivered at K and /K rising edges.
3. /R and /W must meet setup/hold times around the rising edges (low to high) of K and are registered at the
rising edge of K.
4. This device contains circuitry that will ensure the outputs will be in high-Z during power-up.
5. Refer to state diagram and timing diagrams for clarification.
6. When clocks are stopped, the following cases are recommended; the case of K = low, /K = high, C = low and
/C = high, or the case of K = high, /K = low, C = high and /C = low. This condition is not essential, but permits
most rapid restart by overcoming transmission line charging symmetrically.
