Description
General part information
TMUX121 Series
The TMUX121 is a high performance bidirectional 2-channel, 2:1 (SPDT) switch that supports both differential and single ended signals. The TMUX121 is an analog passive switch which features power-off protection forcing all I/O pins to be in high-impedance mode when power is not present on the V DD pin. The select and enable pins of the TMUX121 compatible with 1.8 V and 3.3 V control voltage, 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 TMUX121 an excellent choice for supporting switching a wide range of analog signals and digital communication protocol standards, including high-speed standards such as I 3C.
The TMUX121 comes in a small 10-pin UQFN package with only 1.8 mm × 1.4 mm in size, which makes it useful when PCB area is limited.
