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 VCC terminals must be externally wired together to prevent internal damage during VCC power-on/off cycles.
2. For operation above 25
°C free-air temperature, derate linearly at the rate of 20 mW/°C.
