Layout Guidelines (continued)

Figure 12 illustrates an example of a PCB layout with the TMUX110x. Some key considerations are:

•

Decouple the VDD pin with a 0.1-µF capacitor, placed as close to the pin as possible. Make sure 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 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.
