Notes:

1. CE may be delayed up to tACC - tCE after the address transition without impact on tACC.

2. OE may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE or by tACC - tOE after an address change

without impact on tACC.

3. tDF is specified from OE or CE, whichever occurs first (CL = 5 pF).

4. This parameter is characterized and is not 100% tested.
