7.4 Device Functional Modes
7.4.1 Inverting Mode of Operation
During the inverting mode of operation, INB is used as the control input and the polarity of OUT is reversed with
respect to INB. A timing diagram of this mode is shown in Figure 11. The IN pin is not used in this mode of
operation and should be pulled up to VCC.

7.4.2 Non-inverting Mode of Operation
During the non-inverting mode of operation, IN is used as the control input and the polarity of OUT is the same
with respect to IN. A timing diagram of this mode is shown in Figure 12. The INB pin is not used in this mode of
operation and should be connected to IN_REF.
