2.5.4. Digital Inputs
You can connect the digital inputs to current sourcing or current sinking devices but you must connect all
four inputs in the same configuration. Refer to
Figure 2-44 and Figure 2-43 . The digital inputs are not
designed for high-voltage isolation applications. They should only be used with ground-referenced
circuits.
