3.4. Digital Inputs [-EB1]
Input bits are arranged in groups of 4 and each group shares a common pin. This lets a group be connected to
current sourcing or current sinking devices, based on the connection of the common pin in that group.
To be able to connect an input group to current sourcing devices, connect the input group's common pin
to the power supply return (-). Refer to Figure
.
To be able to connect an input group to current sinking devices, connect the input group's common pin to
the power supply source (+). Refer to Figure
The digital inputs are not designed for high-voltage isolation applications. They should only be used with
ground-referenced circuits.
