The TMUX131 device is a high performance bidirectional 2-channel, 3:1 multiplexer that supports both differential and single ended signals. The TMUX131 is an analog passive multiplexer which features power-off protection forcing all I/O pins to be in high-impedance mode when power is not present on the VDD pin. The select pins of the TMUX131 are compatible with 1.8 V and 3.3 V control logic, allowing them to be directly interfaced with the general purpose I/O (GPIO) from low voltage processors. This, along with the low on-resistance and low on-capacitance of the device, make the TMUX131 an excellent device for supporting switching a wide range of analog signals and digital communication protocol standards, including high-speed standards such as I 3C.

The TMUX131 comes in a small 12-pin VQFN package with only 1.8 mm × 1.8 mm in size, which makes it useful when PCB area is limited.
