Specifications subject to change without notice.
Sample tested during initial release and after any redesign or process change that may affect this parameter. All input signals are specified with tr = tf = 5 ns (10% to
90%) and timed from a voltage level of 1.6 V.
See timing diagram below and Serial Interface section of this data sheet.
Measured with the load circuit in Load Circuit for Timing Specifications and defined as the time required for the output to cross 0.8 V or 2.4 V.
Derived from the measured time taken by the data outputs to change 0.5 V when loaded with the circuit in Load Circuit for Timing Specifications. The measured
number is then extrapolated back to remove the effects of charging or discharging the 50 pF capacitor. This means that the time quoted in the timing characteristics
is the true bus relinquish time of the part and is independent of the bus loading.
