Functional operability under any of these conditions is not necessarily implied. Exposure to absolute maximum rating conditions for extended periods of time may affect device reliability. EXPLANATION OF TEST LEVELS I. Devices are 100% production tested at 25 °C and guaranteed by design and characterization testing for the commercial operating temperature range (–40 °C to +85°C). II. Parameter is guaranteed by design and/or characterization testing. III. Parameter is a typical value only. THERMAL CHARACTERISTICS Thermal Resistance 48-Lead LQFP θ JA = 57ºC/W θJC = 28ºC/W |
