The H port signal from the controller can go to one of the 4 peripheral ports depending on the select inputs S0 and S1. The V_BIAS and V_REF can be determined from Section 6.3.

1. Recommended Input Conditions
   • For specified high and low levels for all the input control pins, see V_IH and V_IL in Section 6.3.
   • Inputs are not overvoltage tolerant and should be below the valid V_DD.
2. Recommend Input/Output Conditions
   • The absolute maximum continuous on state switch current for any I/O should not exceed ±100 mA.
   • The I/O voltage range should not be above V_DD and below ground.
