SLASEP7 May 2020 TMUXHS4212
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 device to work; otherwise, it disables the outputs. This pin can be driven by a processor. The expectation is that one side of the device has AC coupling capacitors. Table 2 provides information on expected values to perform properly.
|AXp/n, BXp/n, CXp/n CM input voltage||0 V to 1.8 V|
|Control/OEn pin max voltage for low||0.5 V|
|Control/OEn pin min voltage for high||1.42 V|
|AC coupling capacitor||75 nF to 265 nF|
|RBIAS (Figure 9) when needed||1 kΩ to 100 kΩ|
