7.1.2 Input and Output Configurations
Figure 7-3 to Figure 7-5 illustrate examples of the various input and output configurations.

Figure 7-4 Monitoring the Same Voltage as VDD with Wired-OR Logic
Figure 7-5 Monitoring a Voltage Other Than VDD with Wired-OR LogicNote that the SENSE input can also monitor voltages that are higher than VSENSE (max) or that may not be designed for rail voltages with the use of an external resistor divider network. If a resistor divider is used to reduce the voltage on the SENSE pin, make sure that the ISENSE current is accounted for so the accuracy is not unexpectedly affected. As a general approximation, the current flowing through the resistor divider to ground must be greater than 100 times the current going into the SENSE pin. See application report Optimizing Resistor Dividers at a Comparator Input (SLVA450) for a more in-depth discussion on setting an external resistor divider.
