See Figure 2 and Figure 3. Temperature range for Y version is 40°C to +125°C. Guaranteed by design and characterization, not subject to
production test. All input signals are specified with tr = tf = ns (10% to 90% of V
DD
) and timed from a voltage level of (V

+ V
IH
)/2.

Falling or rising edge as determined by the control bits of the serial word. Strong or weak SDO driver selected via the control register.
2
Daisy-chain and readback modes cannot operate at maximum clock frequency. SDO timing specifications are measured with a load circuit, as shown in Figure 4.
