Timing
Figure 4. Timing for clock, serial-in, serial-out, latch enable and outputs
Correct sampling of the data depends on the stability of the data at SDI on the rising edge of
the clock signal and it is assured by a proper data setup and hold time (tSU(D) and th(D)), as
shown in Figure 4. The same figure shows the propagation delay from CLK to SDO
(tPLH/tPHL). Figure 4 describes also the minimum duration of CLK and LE pulses (tW(CLK)
and tW(L), respectively) and the propagation delay from LE to OUTn (tPLH1/tPHL1 and
tPLH2/tPHL2, respectively). Finally, Figure 5 also defines the turn-on and turn-off time (tof and
tor) of the output voltage.
