Sample tested during initial release to ensure compliance. All input signals are specified with tr = tf = 5 ns (10% to 90% of 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
Interface section and Figure 41 and Figure 42.
Minimum SCLK for specified performance; with slower SCLK frequencies, performance specifications apply typically.
The time required for the output to cross 0.4 V or 2.4 V.
