The TLV380x has two seperate power rails: VCC - VEE for the input stage and VCC - GND for the output stage. This allows for both single and split supply capabilities for the input stage with a seperate ground reference for the LVDS output stage. Split supply operation allows users to apply both positive and negative (bipolar) voltages to the input pins.

When operating from a single supply, the supply voltage range for both the input and output stage is 2.7 V to 5.25 V. When operating from split supply rails, the supply voltage range for the input stage (VCC - VEE) is 2.7 V to 5.25 V, and the supply voltage range for the output stage (VCC - GND) is 2.4 V to 5.25 V. The output logic level is independent of the VCC and VEE levels. The TLV3811(C) is specified for operation from 2.4 V to 5.25 V and can only be operated from a single supply with both inputs and outputs referenced to GND.

Regardless of single supply or split supply operation, proper decoupling capacitors are required. It is recommended to use a scheme of multiple, low-ESR ceramic capacitors from the supply pins to the ground plane for optimum performance. A good combination would be 100 pF, 10 nF, and 1 uF with the lowest value capacitor closest to the comparator.
