Fig.3 Data set-up and hold times.

The shaded areas indicate when the input data may change and be correctly registered. Data input update must be completed within 0.3 ns after the first

rising edge of the clock (tSU;DAT is negative; −0.3 ns). Data must be held at least 2 ns after the rising edge (tHD;DAT = +2 ns).
