IDT7008L IDT [Integrated Device Technology], IDT7008L Datasheet - Page 7

• Manufacturer Part Number: IDT7008L
• Description: HIGH-SPEED 64K x 8 DUAL-PORT STATIC RAM
• Manufacturer: IDT [Integrated Device Technology]

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.
