Notes:
6
1. CE may be delayed up to t ACC - t CE after the address transition without impact on t ACC .
2. OE may be delayed up to t CE - t OE after the falling edge of CE without impact on t CE or by t ACC - t OE after an address change
without impact on t ACC .
3. t DF is specified from OE or CE whichever occurs first (C L = 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 otherwise incorrect data may be
read.
