† Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only, and

functional operation of the device at these or any other conditions beyond those indicated in the “Recommended Operating Conditions” section of

this specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

Caution. 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 to 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
