9.2.1.2 Detailed Design Procedure

The SN74CBTLV3126 can operate without any external components except for the supply decoupling capacitors. TI recommends that the digital control pins (OE) be pulled up to VCC or down to GND to avoid an undesired switch state that could result from the floating pin. All input signals passing through the switch must fall within the Recommend Operating Conditions of the SN74CBTLV3126 including signal range and continuous current. For this design example, with a supply of 3.3 V, the signals can range from 0 V to 3.3 V when the device is powered. This example can also utilize the Powered-off Protection feature, and the inputs can range from 0 V to 3.3 V when VDD = 0 V.
