TMUX1574: About input and output voltage.

A switch that is on behaves like a small resistor (2 Ω).

Unless you have a load that causes a continuous current to flow, the S1A and D1 voltages will be identical.

Hi Wen,

As Clemens mentioned, the TMUX1574 has very low RON of 2-Ohm - besides that  the output will be impacted by your loading conditions.

The TMUX1574 offers very low and flat RON because of the switch structure  (See more details in the video, What are common switch architectures?) and supports bidirectional analog and digital signals on the source (SxA, SxB) and drain (Dx) pins and can pass signals above supply up to VDD.

Hi Clemens Ladisch & Saminah C,

Thanks for answer my question, i want to do switch between 1.8V and 3.3V BUS channels, so i can do my work.

Thank you and best regards,
