Notes
23. 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 V
PWR
.
24. Input capacitance of SI, CS, SCLK, RST, IN[0:3] and WAKE. This parameter is guaranteed by process monitoring but is not production tested.
25. The current must be limited by a series resistance when using voltages > 7.0 V.
26. Pull-down current is with V
SI
> 1.0 V and V
SCLK
> 1.0 V.
27. Pull-up current is with V
CS
< 2.0 V. CS has an active internal pull-up to V
DD
.
28. In Fail-Safe HS[0:3] depends respectively on ON[0:3]. FSI has an active internal pull-up to V
REG
~ 3.0 V.
