Temperature range from −40°C to +125°C.
Typical specifications are tested with V
See the Terminology section.
Guaranteed by characterization.
See the Power vs. Throughput Rate section.
Sample tested during initial release to ensure compliance. All timing specifications given are with a 10 pF load capacitance. With a load capacitance greater than this
value, a digital buffer or latch must be used.
Guaranteed by characterization. All input signals are specified with tr = tf = 2 ns (10% to 90% of V
Mark/space ratio for the SCLK input is 40/60 to 60/40.
