This published maximum operating ambient temperature should be used only as a system design guideline. All device operating
parameters are guaranteed only when the junction temperature lies within the specified range.

and power dissipation specifications in the system design to prevent device junction temperatures from exceeding the rated
specification. System designers should be aware that device junction temperatures can be significantly influenced by the board layout
and surrounding devices. Conformance to the device junction temperature specification can be verified by physical measurement in
the customer’s system using the Y

parameter, the device power dissipation, and the method described in EIA/JESD Standard 51-2.
