NOTES:
1. Transition is measured 0mV fromLow or High-impedance voltage fromthe Output Test Load (Figure 2).
2.
This parameter is guaranteed by device characterization but not production tested.
3.
For MASTER/SLAVE combination, t
WC
= t
BAA
+ t
WR
+ t
WP
, since R/
W
= V
IL
must occur after t
BAA.
4.
The specification for t
DH
must be met by the device supplying write data to the RAMunder all operation conditions. Although t
DH
and t
OW
values will very over voltage and
temperature, the actual t
DH
will always be smaller than the actual t
OW
.
5.
'X' in part number indicates power rating (SA or LA).
