Applying a logic HIGH voltage signal enables the part. A logic LOW voltage signal places the the device in shutdown. These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) (3) VIN Pin Voltage -0.3V to 6.0V EN Pin Voltage -0.3V to (VIN+0.3V) w/ 6.0V max Continuous Power Dissipation(4) Internally Limited Junction Temperature (TJ-MAX) 150ºC Storage Temperature Range -65ºC to +150º C Maximum Lead Temperature(5) 265ºC Human Body Model 2.0kV ESD Rating(6) Machine Model 200V (1) Absolute Maximum Ratings indicate limits beyond which damage to the component may occur. Operating Ratings are conditions under which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. (2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and specifications. (3) All voltages are with respect to the potential at the GND pins. (4) Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at TJ=150ºC (typ.) and disengages at TJ=140ºC (typ.). (5) For detailed information on soldering requirements and recommendations, please refer to National Semiconductor's Application Note 1187 (AN-1187): Leadless Leadframe Package (LLP). (6) The Human body model is a 100pF capacitor discharged through a 1.5k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin.
