IDT70V27 Integrated Device Technology, IDT70V27 Datasheet - Page 8

• Manufacturer Part Number: IDT70V27
• Description: 32k X 16 3.3v Dual-port Ram
• Manufacturer: 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 RAM, CE = V
4. 'X' in part numbers indicates power rating (S or L).
5. Refer to Chip Enable Truth Table.
