ABSOLUTE MAXIMUM RATINGS
DISSIPATION RATING TABLE
SLVS798F – JANUARY 2008 – REVISED NOVEMBER 2008 ........................................................................................................................................... www.ti.com
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 appropriate logic
voltage level, preferably either VCC or ground. Specific guidelines for handling devices of this type are contained in the publication
Guidelines for Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
