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 master clock input is 40/60 to 60/40.
3The CONVST pulse width will here only apply for normal operation. When the part is in power-down mode, a different CONVST pulse width will apply (see Power-
Down section).
4Measured 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.
5t
9 is derived form the measured time taken by the data outputs to change 0.5 V when loaded with the circuit of Figure 1. The measured number is then extrapolated
back to remove the effects of charging or discharging the 50 pF capacitor. This means that the time, t 9, quoted in the timing characteristics is the true bus relinquish
time of the part and is independent of the bus loading.
6The typical time specified for the calibration times is for a master clock of 4 MHz. For the L version the calibration times will be longer than those quoted here due to
the 1.8 MHz master clock.
Specifications subject to change without notice.
