The TLV701x and TLV702x have a Power-on-Reset (POR) circuit. While the power supply (VS) is ramping up or ramping down, the POR circuitry will be activated.
For the TLV701x, the POR circuit will hold the output low (at VEE) while activated.
For the TLV702x, the POR circuit will keep the output high impedance (logical high) while activated.
When the supply voltage is greater than, or equal to, the minimum supply voltage, the comparator output reflects the state of the differential input (VID).
