AC Read Characteristics

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.
