NOTES

1Sample tested at 25

°C to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of V DD) and timed from a voltage level of 1.6 V.

2Mark/Space ratio for the SCLK input is 40/60 to 60/40. See Serial Interface section.

3Measured with the load circuit of Figure 1 and defined as the time required for the output to cross 0.8 V or 2.4 V with V

DD = 5 V

± 10% and time for an output to

cross 0.4 V or 2.0 V with VDD = 3 V

± 10%.

4t

8 is derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 1. The measured number i s then extrapolated

back to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, t 8, quoted in the timing characteristics is the true bus relinquish

time of the part and is independent of the bus loading.

Specifications subject to change without notice.
