The TLV902xL features an open-drain (also commonly called open collector) sinking-only output stage enabling the output logic levels to be pulled up to any voltage up to 5.5V, independent of the comparator supply voltage (VS). The open-drain output also allows logical ORing of multiple open drain outputs and logic level translation.
TI recommends setting the pull-up resistor current to between 100uA and 1mA. Lower pull-up resistor values helps decrease the rising edge rise time, but at the expense of increasing VOL and higher power dissipation. The rise time is dependent on the time constant of the total pull-up resistance and total load capacitance. Large value pull-up resistors (> 1MΩ) creates an exponential rising edge due to the RC time constant and increase the rise time.
Unused open drain outputs can be left floating, or can be tied to the V– pin if floating pins are not allowed.
The open-drain output protection consists of a ESD clamp between the output and V- to allow the output to be pulled to any voltage up to a maximum of 5.5V, even if the pullup voltage exceeds VS.
