The TLV360x have a Power-on-Reset (POR) circuit which provides system designers a known start-up condition for the output of the comparators. When the power supply (VCC) is ramping up or ramping down, the POR circuit will be active when VCC is below V_POR. When active, the POR circuit holds the output low at VEE. When VCC is greater than or equal to V_POR as stated in Section 6.5 , the comparator output reflects the state of the input pins.

Figure 7-1 shows how the TLV360x outputs respond for VCC rising. The input is configured with a logic high input to highlight the transition from the POR circuit control (logic low output) to a standard comparator operation where the output reflects the input condition. Note how the output goes high when VCC reaches 2.1V.
