The input voltage range extends from 200mV below VEEI to 200mV above VCCI, maximizing input dynamic range. The input stage has ESD clamps to the VCCI 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. To avoid damaging the inputs when exceeding the recommended input voltage range, an external resistor must be used to limit the current to less than 1mA. Likewise, unlike high-speed amplifiers, the comparator inputs do not have clamping diodes between them. This allows for applications where the input differential voltage can match the supply voltage (V+). However, when the input differential voltage increases to 2V, bias current increases to the nA range occur. This is a result of internal circuitry intended to minimize propagation delay increases due to large input underdrive amplitudes.
