IDT70V28L Integrated Device Technology, IDT70V28L Datasheet - Page 5

• Manufacturer Part Number: IDT70V28L
• Description: High-speed 3.3v 64k X 16 Dual-port Static Ram
• Manufacturer: Integrated Device Technology

NOTES:
1. At Vcc
2. Refer to Truth Table I -
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 Truth Table I - Chip Enable.
