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. All control inputs in the truth table 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. It is recommended that (K) = /(
K
) = (C) = /(
C
) when clock is stopped. This is not essential, but
permits most rapid restart by overcoming transmission line charging symmetrically.
7. A1 refers to the address input during a WRITE or READ cycle. A2 refers to the next internal
burst address in accordance with the linear burst sequence.
