Float delays are measured with 5 pF AC loads. Transition is measured at ±200 mV from steady state active levels.

Note:
1 The XC17V00 RESET/OE input polarity is programmable. The RESET/OE input is shown in the timing diagram with active-high RESET polarity.
2. If BUSY is inactive (Low) during a rising CLK edge, then new DATA appears at time T
Timing specifications are identical for both polarity settings.
during a rising CLK edge, then there is no corresponding change to DATA.
