2.6.2. 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
and
. The digital
inputs are not designed for high-voltage isolation applications. They should only be used with
ground-referenced circuits.
