11.1 Layout Guidelines

Thin traces can be used on the input due to the low-current logic that is typically used to drive the ULQ200xA-Q1 devices. Take care to separate the input channels as much as possible, as to eliminate crosstalk. TI recommends thick traces for the output to drive whatever high currents that may be needed. Wire thickness can be determined by the current density of the trace material and desired drive current.

Because all of the channels currents return to a common emitter, it is best to size that trace width to be very wide. Some applications require up to 2.5 A.
