The following figure illustrates an example of a
PCB layout with the TMUX582F-SEP.
Some key considerations are as follows:
- Decouple the VDD pin with a 0.1µF capacitor, placed as close to the
pin as possible.Vss pin must be set to GND. Ensure that the
capacitor voltage rating is sufficient for the VDD supply.
- Keep the input lines as short as possible.
- Use a solid ground plane to help distribute heat and reduce electromagnetic interference (EMI) noise pickup.
- Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if possible, and only make perpendicular crossings when necessary.
