† 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.

NOTES:

1. All voltage values are with respect to GND.

2. The maximum operating junction temperature is internally limited. Uses the dissipation rating table to operate below this

temperature.

‡ The algebraic convention, in which the least positive (most negative) limit is designated as minimum, is used in this data sheet for differential

input voltage, voltage at any bus terminal (separately or common mode), operating temperature, input threshold voltage, and common-mode

output voltage.
