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 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.
