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). As provided in Table 8-1, the select pins (SELx) and enable pin (EN) determines which switch path to turn on. The following conditions must be satisfied for the switch to stay in the ON condition:

• The difference between the supples (V_DD – V_SS) must be greater than or equal to 8 V, with a minimum V_DD of 5 V.
• The input signals on the source (Sx) or the drain (Dx) must be be between V_DD+ V_T and V_SS – V_T.
• The logic control (SELx and EN) must have selected the switch.
