6.4.1.1 TLV18x2-EP Rail-to-Rail Input

The TLV18x2-EP input voltage range extends from 200mV below V- to 200mV above V+. The differential input voltage (VID) can be any voltage within these limits. No phase-inversion of the comparator output occurs when the input voltages stay within the specified range.

For the TLV1812-EP (Push-Pull), the inputs have ESD clamps to the V+ supply line and therefore the input voltages must not exceed the supply voltages by more than 200mV. Do not apply signals to the rail to rail inputs with no supply voltage.

For the TLV1822-EP (Open-Drain), the inputs have weak clamps to the V+ supply line. Do not apply signals to the rail to rail inputs with no supply voltage.
