HIGH-SPEED 4K x 16 DUAL-PORT STATIC RAM
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".
