Switching Waveforms[25, 26, 27]
Notes:
24.tCHZ, tCLZ, are specified with a load capacitance of 5 pF as in part (b) of AC Test Loads. Transition is measured ± 100 mV from steady-state voltage.
25.Q00 refers to output from address A0. Q01 refers to output from the next internal burst address following A0, i.e., A0+1.
26.Outputs are disabled (High-Z) one clock cycle after a NOP.
27.In this example, if address A2 = A1 then data Q2 0= D10 and Q21 = D11. Write data is forwarded immediately as read results.This note applies to the whole diagram.
