The TLV1H103-SEP is designed for operation from 2.4V to 5.5V. While most applications require single supply operation where VEE is connected to the ground and VCC is connected to the intended power supply level, the comparators can also be operated with split supplies. One caution when using split supplies is that the output logic levels are determined by the VCC and VEE levels. For example, if split supplies of +/- 2.5V are used, the output levels are 2.5V and -2.5V accordingly. In addition, the logic level of the LE/HYS pin is also referenced to VEE. This means that the external hysteresis resistor or voltage source on the TLV1H103-SEP needs to be connected between the LE/HYS pin and VEE (not to ground) for proper operation.

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