This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. THERMAL RESISTANCE θJA is specified for worst-case mounting conditions, that is, θJA is specified for a device in socket for the PDIP package; θJA is specified for a device soldered to a printed circuit board (PCB) for the SOIC package.
