DYNAMIC ELECTRICAL CHARACTERISTICS

Table 4. Dynamic Electrical Characteristics

Characteristics noted under conditions 3.0V ≤ VCC ≤ 5.5V, 7.0V ≤ VBAT ≤ 20V, - 40°C ≤ TA ≤ 125°C, GND = 0V, unless

otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25°C under nominal conditions, unless

otherwise noted.

Notes

46. Maximum setup time required for the 10XS3535 is the minimum guaranteed time needed from the microcontroller.

47. Rise and Fall time of incoming SI, CS, and SCLK signals suggested for design consideration to prevent the occurrence of double pulsing.

48. Time required for output status data to be available for use at SO. 1.0 kΩ on pull-up on CS.

49. Time required for output status data to be terminated at SO. 1.0 kΩ on pull-up on CS.
