AC Read Waveforms
Notes:
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 in t
ACC
.
3. t
DF
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.
