OUT00–OUT07 are powered by to +K1, and OUT08–OUT15 are powered by +K2.
K1 and K2 can each be up to 36 V, and should be able to supply up to 1.6 A. +K1 and
+K2 don't have to be same. The actual voltage depends on the requirements of the loads
you plan to connect to the digital outputs.
All the sinking or sourcing current, which could
be up to 1.6 A per bank of outputs, is returned
through the GND pins. Be sure to use a suitably

sized GND as explained in Section 2.2.1, and
keep the distance to the power supply as short as
possible.
For the H bridge, which is shown in Figure 12,
