9.5.2 Layout Example

Figure 9-8 shows an example of a PCB layout with the TMUX111x. Some key considerations are:

• Decouple the VDD pin with a 0.1µF 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.
