TMP01 UNDERb and OVERb Outputs

When the TMP01 is powered up, what is the timing of the UNDERb and OVERb pins? Before they settle, are they random or are they pulled high/low?

The UNDERb and OVERb pins are open collector outputs. The output settling time depends on the value of pull-up resistors used. A strong pull-up (Low value resistor) will give a faster power-on settling time but this also causes alot of current to be sunk by the part which could cause self-heating in the device. A pull-up resistor in the range 4k7 to 10k is recommended on each UNDERb and OVERb output pin.
