7 / 17 page  6.42 IDT709089/79S/L High-Speed 64/32K x 8 Synchronous Dual-Port Static RAM Industrial and Commercial Temperature Ranges 7 NOTES: 1. Transition is measured 0mV from Low or High-impedance voltage with the Output Test Load (Figure 2). This parameter is guaranteed by device characterization, but is not production tested. 2. The Pipelined output parameters (tCYC2, tCD2) apply to either or both left and right ports when FT/PIPE = VIH. Flow-through parameters (tCYC1, tCD1) apply when FT/PIPE = VIL for that port. 3. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE) and FT/PIPE. FT/PIPE should be treated as a DC signal, i.e. steady state during operation. 4. 'X' in part number indicates power rating (S or L).
