NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage from the 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 RAM under 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).
