Notes 1. This parameter also applies to a -C80 or -C71 part when operated with tCYCLE =3.33 ns.
2. This parameter also applies to a -C80 part when operated with tCYCLE =2.81 ns.
3. tQ,MIN and tQ,MAX for other tCYCLE values can be interpolated between or extrapolated from the timings at the
3 specified tCYCLE values.
