DC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range
NOTES:
1. 'X' in part numbers indicates power rating (S or L).
2. V
3. At f = f
4. f = 0 means no address or control lines change.
5. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
6. Refer to Chip Enable Truth Table.
