In Normal mode operation, signals of up to V_FP and V_FN can be passed through the switch from source (Sx) to drain (Dx) or from drain (Dx) to source (Sx). The following conditions must be satisfied for the switch to stay in the ON condition:

• The difference between the primary supplies (V_DD – V_SS) must be higher or equal to 8 V.
• V_FP must be between 3 V and V_DD, and V_FN must be between V_SS and 0 V.
• The input signals on the source (Sx) or the drain (Dx) must be between V_FP+ V_T and V_FN – V_T.
