Table 4. Dynamic Electrical Characteristics (continued)
Characteristics noted under conditions 6.0V ≤ V_PWR ≤ 20V, 3.0V ≤ V_DD ≤ 5.5V, - 40°C ≤ T_A ≤ 125°C, GND = 0V, unless
otherwise noted. Typical values noted reflect the approximate parameter means at T_A = 25°C under nominal conditions, unless
otherwise noted.

Notes
32. Parameters guaranteed by design.
33. Value guaranteed per statistical analysis
34. RST low duration measured with outputs enabled and going to OFF or disabled condition.
35. Maximum setup time required for the 35XS3400 is the minimum guaranteed time needed from the microcontroller.
36. Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.
37. Time required for output status data to be available for use at SO. 1.0kΩ on pull-up on CS.
38. Time required for output status data to be terminated at SO. 1.0kΩ on pull-up on CS.
