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 condition" is not implied. Exposure to absolute-
maximum-rated conditions for extended periods may affect device reliability.
Notes: 1. The input and output negative-voltage ratings may be exceeded if the input and output clamp
current ratings are observed.
2. The input and output positive-voltage ratings may be exceeded up to 4.6 V if the input and output
clamp-current ratings are observed.
3. The maximum power dissipation is calculated using a junction temperature of 150
C and board
trace length of 750 mils.
