IDT70V08 Integrated Device Technology, IDT70V08 Datasheet - Page 7

• Manufacturer Part Number: IDT70V08
• Description: 64k X 8 3.3v Dual-port Ram
• Manufacturer: Integrated Device Technology

AC Electrical Characteristics Over the
Operating Temperature and Supply Voltage Range
NOTES:
1. Transition is measured 0mV from Low or High-impedance voltage with Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. To access RAM, CE = V
4. 'X' in part numbers indicates power rating (S or L).
