3 Description

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 oncapacitance

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

I3C.

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.
