IDT7024L IDT [Integrated Device Technology], IDT7024L Datasheet - Page 7

• Manufacturer Part Number: IDT7024L
• Description: HIGH-SPEED 4K x 16 DUAL-PORT STATIC RAM
• Manufacturer: IDT [Integrated Device Technology]

NOTES:
1. Transition is measured 500mV from Low or High-impedance voltage with the Output Test Load (Figure 2).
2. This parameter is guaranteed by device characterization, but is not production tested.
3. To access RAM,
4. "X" in part numbers indicates power rating (S or L).
