The rail-to-rail input has ESD clamps to both VCCI and VEEI, as shown in the Functional Block Diagram, and therefore the input voltage must not exceed the VCCI and VEEO supply voltages by more than 200mV. Do not apply signals directly to the inputs with no supply voltage without series input current limiting.
If the inputs are to be connected to a low impedance source, such as a power supply or buffered reference line, or a signal that can be present while the power is off, TI recommends adding a current-limiting resistor in series with the input to limit any transient currents in case the clamps conduct. The current must be limited to 10mA or less. This series resistance can be part of any resistive input dividers or networks.
The TLV187x push-pull output has ESD clamps to both VCCO and VEEO, as shown in the Functional Block Diagram. The output must not exceed the output supply rails by more than 200mV. Output excursions can be caused by output trace ringing, inductive load kick-back, or externally induced transients.
Due to the high (<10ns) output edge rates, unless matched impedance traces are used, a small series resistor (33 to 100Ω) can be added in series with the output trace to dampen unmatched trace reflections. See the Layout Example in the Layout Guidelines section.
