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.
Package D only:
The device may be hand soldered provided that heat is applied only to the solder pad and no contact is made
between the tip of the solder iron and the device lead. The maximum time heat should be applied to the device is 5 seconds.
