H : HIGH, L : LOW, × : don’t care, ↑ : rising edge. 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 edge (LOW to HIGH) of K. All control inputs are registered during the rising edge of K. 4. This device contains circuitry that ensure the outputs to be in high impedance during power-up. 5. Refer to state diagram and timing diagrams for clarification. 6. A1 refers to the address input during a WRITE or READ cycle. A2, A3 and A4 refers to the next internal burst address in accordance with the linear burst sequence. 7. 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. |
