Parameter Test Conditions Typical Limits Units tCS Minimum CS Pulse Width 10 ns (min) tSU CS to SCLK Setup Time 10 ns (min) tEN Delay from CS Until SDATA TRI-STATE® Disabled (1) 20 ns (max) VA = +2.7V to +3.6V 40 ns (max) tACC Data Access Time after SCLK Falling Edge (2) VA = +4.75V to +5.25V 20 ns (max) tCL SCLK Low Pulse Width 0.4 x tSCLK ns (min) tCH SCLK High Pulse Width 0.4 x tSCLK ns (min) VA = +2.7V to +3.6V 7 ns (min) tH SCLK to Data Valid Hold Time VA = +4.75V to +5.25V 5 ns (min) 25 ns (max) VA = +2.7V to +3.6V 6 ns (min) tDIS SCLK Falling Edge to SDATA High Impedance (3) 25 ns (max) VA = +4.75V to +5.25V 5 ns (min) tPOWER-UP Power-Up Time from Full Power-Down 1 µs (1) Measured with the timing test circuit shown in Figure 2 and defined as the time taken by the output signal to cross 1.0V. (2) Measured with the timing test circuit shown in Figure 2 and defined as the time taken by the output signal to cross 1.0V or 2.0V. (3) tDIS is derived from the time taken by the outputs to change by 0.5V with the timing test circuit shown in Figure 2. The measured number is then adjusted to remove the effects of charging or discharging the output capacitance. This means that tDIS is the true bus relinquish time, independent of the bus loading.
