7 / 18 page 6.42 IDT7026S/L High-Speed 16K x 16 Dual-Port Static RAM Military, Industrial and Commercial Temperature Ranges 7 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 and SEM = VIH. To access semaphore, CE = VIH and SEM = VIL. 4. 'X' in part numbers indicates power rating (S or L).
