The inputs incorporate internal ESD protection circuits to (V+) and (V-). Voltages on the inputs are limited to 0.1V beyond the rails.

When connecting 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 if the clamps conduct. Limit the current to 10mA or less. One form of series resistance is any resistive input dividers or networks.
