12.1 Layout Guidelines

Thin traces can be used on the input due to the low-current logic that is used to drive the SNx545xB devices. Take care to separate the input channels to eliminate crosstalk. These traces are recommended for the output to be able to drive high currents. Be sure to connect ground or VCC to any unused input channels, and use a bypass capacitor on the VCC pin to prevent any power glitches.
