Texas Instruments TMUX131 3:1 2-Channel Multiplexer

Texas Instruments TMUX131 3:1 2-Channel Multiplexer is a high-performance bi-directional 2-channel 3:1 multiplexer that supports differential and single-ended signals. The TMUX131 is an analog passive multiplexer with power-off protection that forces I/O pins to be in high-impedance mode when power is not on the V_DD pin. The select pins of the TMUX131 are compatible with 1.8V and 3.3V control logic. This feature allows them to be directly interfaced with the general-purpose I/O (GPIO) from low-voltage processors. This feature and the device’s low on-resistance and on-capacitance 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 I³C. The Texas Instruments TMUX131 comes in a small 12-pin VQFN package with only 1.8mm × 1.8mm in size, which makes it useful when the PCB area is limited.
