latched status is cleared and the TLV3603-EP output can continue to track the status of the input pins.

8 Power Supply Recommendations

The TLV3603-EP 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 TLV3603-EP 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.
