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 in tACC
.
.
3. tDF is specified from OE or CE wichever occurs first (CL = 5 pF).
4. This parameter is characterized and is not 100% tested.
5. If CE is de-asserted, it must remain de-asserted for at least 50ns during read operations other-
wise incorrect data may be read.
