6.4.2.3 Input Protection

The input bias current is typically 5pA for input voltages between V+ and V-. The comparator inputs are protected from negative voltage by the internal ESD diodes connected to V-. As the input voltage goes under V-, or above the input Absolute Maximum ratings, the protection diodes become forward biased and begin to conduct causing the input bias current to increase exponentially. Input bias current doubles for each 10°C temperature increase.

If the inputs are to be connected to a low impedance source, such as a power supply or buffered reference line, TI recommends adding a current-limiting resistor in series with the input to limit any transient currents when the clamps conduct. See the ESD section for more information.
