In Normal Mode operation, signals of up to V_DD and V_SS can be passed through the switch from source (Sx) to drain (Dx) or from drain (Dx) to source (Sx). The select (SELx) pins determine which switch path to turn on, according to the Truth Table. 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 greater than or equal to 10 V. With a minimum V_DD of 10 V.
• The input signals on the source (Sx) or the drain (Dx) must be between V_DD and V_SS.
• The logic control (SELx) must have selected the switch.
