TIMING SPECIFICATIONS
Guaranteed by characterization.
All input signals are specified with tr = tf = 5 ns (10% to 90% of VDD) and timed from a voltage level of 1.6 V.
VDD = 2.35 V to 5.25 V; TA = TMIN to TMAX, unless otherwise noted.

1 Mark/space ratio for SCLK input is 40/60 to 60/40.
2 Minimum fSCLK at which specifications are guaranteed.
3 Measured with the load circuit in Figure 2 and defined as the time required for the output to cross VIH or VIL voltage.
4 Measured with a 50 pF load capacitor.
5 T10 is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit in Figure 2. The measured number is then extrapolated
back to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, t10, quoted in the timing characteristics is the true bus relinquish
time of the part and is independent of the bus loading.
