6 / 13 page ![]() AT49F1024/1025 6 AC Read Waveforms(1)(2)(3)(4) Notes: 1. CE may be delayed up to t ACC - tCE after the address transition without impact on tACC. 2. OE may be delayed up to t CE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change without impact on t ACC. 3. t DF is specified from OE or CE whichever occurs first (CL = 5 pF). 4. This parameter is characterized and is not 100% tested. Input Test Waveforms and Measurement Level t R, tF < 5 ns Output Test Load Note: 1. This parameter is characterized and is not 100% tested.
