In Normal mode operation, signals of up to V_DD and V_SS can be passed through the switch from source (Sx) to drain (D or Dx) or from drain (D or Dx) to source (Sx). The address (Ax) pins and the enable (EN) pin determines which switch path to turn on, according to Table 9-1 and Table 9-2. 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 8 V. With a minimum V_DD of 5 V.
• The input signals on the source (Sx) or the drain (D or Dx) must be between V_DD+ V_T and V_SS – V_T.
• The logic control (Ax and EN) must have selected the switch.
