Notes
1. Operation within the t
RCD
(max.) limit ensures that t
RAC
(max.) can be met. t
RCD
(max.) is specified as a reference point only. If t
RCD
is greater than the specified t
RCD
(max.) limit, then access time is controlled by t
CAC
.
2. Operation within the t
RAD
(max.) limit ensures that t
RAC
(max.) can be met. t
RAD
(max.) is specified as a reference point only. If t
RAD
is greater than the specified t
RAD
(max.) limit, then access time is controlled by t
AA
.
3. Measured with the specified current load and 100pF.
4. Either t
RCH
or t
RRH
must be satisfied for a read cycle.
5. t
OFF
(max) and t
OEZ
(max) define the time at which the output achieves the open circuit condition and are not referenced to output
voltage levels.
6. Either t
CDD
or t
OED
must be satisfied.
