AC Electrical Characteristics Over the Operating Temperature Range

(VDD = 3.3V ± 0.3V)
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 (t
CYC2, tCD2) apply to either or both the Left and Right ports when FT/PIPE = VIH. Flow-through parameters (tCYC1, tCD1) apply
when FT/PIPE = V
IL for that port.
3. All input signals are synchronous with respect to the clock except for the asynchronous Output Enable (OE), FT/PIPE
R, and FT/PIPEL.
