SLES023C – DECEMBER 2001 – REVISED JANUARY 2005

This device contains circuits to protect its inputs and outputs against damage due to high static voltages

or electrostatic fields. These circuits have been qualified to protect this device against electrostatic

discharges (ESD) of up to 2 kV according to MIL-STD-883C, Method 3015; however, it is advised that

precautions be taken to avoid application of any voltage higher than maximum-rated voltages to these

high-impedance circuits. During storage or handling, the device leads should be shorted together or the

device should be placed in conductive foam. In a circuit, unused inputs should always be connected to

devices of this type are contained in the publication Electrostatic Discharge (ESD) (SSYA010) available

from Texas Instruments.
