2 / 8 page ![]() Absolute Maximum Ratings (Note 1) If Military/Aerospace specified devices are required, please contact the National Semiconductor Sales Office/ Distributors for availability and specifications. ESD Tolerance (Note 2) Human Body Model 2KV Machine Model 200V V IN Differential 30V Supply Voltages 30V or ±15V Voltage at Input Pins −0.3V to 30V Storage Temperature Range −65˚C to +150˚C Junction Temperature (Note 3) +150˚C Soldering Information Infrared or Convection (20 sec.) 235˚C Wave Soldering (10 sec.) 260˚C Operating Ratings (Note 1) Supply Voltage, V S 5V to 30V Temperature Range (Note 3) −40˚C to +85˚C Package Thermal Resistance (Note 3) 5-Pin SOT23 168˚C/W Electrical Characteristics Unless otherwise specified, all limits are guaranteed for T A = 25˚C, VS = 5V, V − = 0V, V CM =V +/2=V O. Boldface limits apply at the temperature extremes.

Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Note 2: Human Body Model, applicable std. MIL-STD-883, Method 3015.7. Machine Model, applicable std. JESD22-A115-A (ESD MM std. of JEDEC) Field-Induced Charge-Device Model, applicable std. JESD22-C101-C (ESD FICDM std. of JEDEC). Note 3: The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at any ambient temperature is PD =(TJ(MAX) -TA)/ θJA . All numbers apply for packages soldered directly onto a PC board. Note 4: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material. Note 5: All limits are guaranteed by testing or statistical analysis. Note 6: The input common-mode voltage of either input should not be permitted to go below the negative rail by more than 0.3V. The upper end of the common-mode voltage range is VS - 1.5V at 25˚C. www.national.com 2 |
