IDT70T3509M Integrated Device Technology, IDT70T3509M Datasheet - Page 8

• Manufacturer Part Number: IDT70T3509M
• Description: High-speed 2.5v 1024k X 36 Synchronous Dual-port Static Ram With 3.3v Or 2.5v Interface
• Manufacturer: Integrated Device Technology

NOTES:
1. At f = f
2. f = 0 means no address, clock, or control lines change. Applies only to input at CMOS level standby.
3. Port "A" may be either left or right port. Port "B" is the opposite from port "A".
4. V
5. CE
