limited by test equipment. Operation down to -40 ° C can be expected. Test included cold start at this tempera-
ture.
**)
constant air flow or heat sink (e.g. mounted to the backside of the pcb (Attention: please make sure to isolate
heatsink from pcb)) may be required. All components are specified for operation up-to at least +85° C
NOTICE
Stresses above those listed under "Absolute Maximum Ratings" may cause perma-
nent damage to the device. This is a stress rating only and functional operation
of the device at those or any other conditions above those indicated in the op-
eration listings of this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
