1 Sample tested during initial release to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of VDD) and timed from a voltage level of 1.6 V.
All timing specifications given are with a 25 pF load capacitance. With a load capacitance greater than this value, a digital buffer or latch must be used. See Serial
2 Minimum SCLK for specified performance; with slower SCLK frequencies, performance specifications apply typically.
3 The time required for the output to cross 0.4 V or 2.4 V.
