PCB layout considerations

For correct operation, it is advised to add 10 nF decoupling capacitors as close as possible

to the power supply pins.

Minimizing the leakage from sensitive high impedance nodes on the inputs of the TSU10x

series can be performed with a guarding technique. The technique consists of surrounding

high impedance tracks by a low impedance track (the ring). The ring is at the same electrical

potential as the high impedance node.

Therefore, even if some parasitic impedance exists between the tracks, no leakage current

can flow through them as they are at the same potential (see Figure 38).
