t12  
1 Sample tested at 25°C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of VCC) and timed from a voltage level of 1.± V.  
2 Mark/space ratio for the DCLK input is ꢀ0/±0 to ±0/ꢀ0.  
3 Measured with the load circuit of Figure 2 and defined as the time required for the output to cross 0.ꢀ V or 2.0 V.  
t12 is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of 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, t12, quoted in the timing characteristics is the true bus relinquish  
time of the part and is independent of the bus loading.
