9.2.1.1 Design Requirements

The TMUXHS4212 can be designed into many different applications. All the applications have certain requirements for the system to work properly. The TMUXHS4212 requires 3.3 V ±10% VCC rail. The OEn pin must be low for the device to work; otherwise, it disables the outputs. A processor can drive the OEn pin. The expectation is that one side of the device has ac coupling capacitors. Table 9-1 provides information on expected values to perform properly.
