Range -65°C to 125°C Soldering Information Lead Temperature (Soldering 10s) 260°C Infrared/Convection Reflow (20sec) 235°C (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications. (3) The human body model is a 100pF capacitor discharged through a 1.5 k Ω resistor into each pin. Operating Ratings (LM3414HV) VIN 4.5V to 65V Junction Temperature Range −40°C to +125°C Thermal Resistance θJA SOIC-8 Package 45°C/W WSON-8 Package 54°C/W Electrical Characteristics (LM3414) VIN = 24V unless otherwise indicated. Typical and limits appearing in plain type apply for TA=TJ= +25°C (1). Limits appearing in boldface type apply over full Operating Temperature Range. Datasheet min/max specification limits are obtained under device test mode and specified by design, test, or statistical analysis.
