(1)

Only M-Grade devices are recommended for operation down to 2.7 V supplies. For 2.7 V-operation, max data rate is 100 Mbps.

(2)

VCCx is the supply voltage, VCC1 or VCC2, for the output channel that is being measured.

Also known as Pulse Skew.

(2)

tsk(o) is the skew between outputs of a single device with all driving inputs connected together and the outputs switching in the same

direction while driving identical loads.

(3)

tsk(pp) is the magnitude of the difference in propagation delay times between any terminals of different devices switching in the same

direction while operating at identical supply voltages, temperature, input signals and loads.
