Figure 2. A.C. Testing Load Circuit (example)
Note:
(1) This parameter is tested initially and after a design or process change that affects the parameter.
(2) A write pulse of less than 20ns duration will not initiate a write cycle.
(3) A timer of duration t
(4) Input rise and fall times (10% and 90%) < 10 ns.
