a. This parameter also applies to a -800 or -711 part when operated with tCYCLE=3.33ns.
b. This parameter also applies to a -800 part when operated with tCYCLE=2.81ns.
c. tQ,MIN and tQ,MAX for other tCYCLE values can be interpolated between or extrapolated from the timings at the 3 specified tCYCLE values.
