2 Maximum rating
Stressing the device above the rating listed inTable 6: Absolute maximum ratings may cause
permanent damage to the device. These are stress ratings only and operation of the device
at these or any other conditions above those indicated inTable 8: Electrical characteristics of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics

2. This value depends from the 4-layer PCB, JEDEC standard test board. For best thermal performance, the
exposed pad PCB area should be connected by via to the PCB groundplane.
