STATIC ELECTRICAL CHARACTERISTICS
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions 6.0 V ≤ VPWR ≤ 20 V, 3.0 V ≤ VDD ≤ 5.5 V, -40 °C ≤ TA ≤ 125 °C, GND = 0 V, unless
otherwise noted. Typical values noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless
otherwise noted.

Notes
20. Upper and lower logic threshold voltage range applies to SI, CS, SCLK, RST, IN[0:3] and WAKE input signals. The WAKE and RST
signals may be supplied by a derived voltage referenced to VPWR.
21. Input capacitance of SI, CS, SCLK, RST, IN[0:3] and WAKE. This parameter is guaranteed by process monitoring but is not production
tested.
22. The current must be limited by a series resistance when using voltages > 7.0 V.
23. Pull-down current is with VSI > 1.0 V and VSCLK > 1.0 V.
24. Pull-up current is with VCS < 2.0 V. CS has an active internal pull-up to VDD.
25. In Fail Safe HS[0:3] depends respectively on ON[0:3]. FSI has an active internal pull-up to VREG ~ 3.0 V.
