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
an appropriated logic voltage level, preferably either V
CC
or ground. Specific guidelines for handling
devices of this type are contained in the publication Electrostatic Discharge (ESD) (SSYA010 ) available
from Texas Instruments.
