Industrial and Commercial Temperature Ranges

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 characteriza-
tion, but is not production tested.
2. The Pipelined output parameters (tCYC2, tCD2) to either the Left or 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), FT/PIPER and FT/PIPEL.
