IDT70V24 IDT [Integrated Device Technology], IDT70V24 Datasheet - Page 10

• Manufacturer Part Number: IDT70V24
• Description: HIGH-SPEED 3.3V 4K x 16 DUAL-PORT STATIC RAM
• Manufacturer: IDT [Integrated Device Technology]

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 SRAM, CE = V
4. The specification for t
5. 'X' in part number indicates power rating (S or L).
