• Manufacturer: Integrated Device Technology

DC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range
NOTES:
1. At Vcc < 2.0V, input leakages are undefined.
2. Refer to Chip Enable Truth Table.
DC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range
NOTES:
1. V
2. At f = f
3. f = 0 means no address or control lines change.
4. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
5. Refer to Chip Enable Truth Table.
