IDT70V35/34S/L (IDT70V25/24S/L)
High-Speed 3.3V 8/4K x 18 (8/4K x 16) Dual-Port Static RAM
Industrial and Commercial Temperature Ranges
AC Electrical Characteristics Over the Operating
Temperature and Supply Voltage Range for 70V25/24(4)
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 = VIL, UB or LB = VIL, and SEM = VIH. To access semaphore, CE = VIH or UB & LB = VIH, and SEM = VIL.
4. 'X' in part number indicates power rating (S or L).
