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 tACC.
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.
