DC Supply Voltage VDD - 0.5 to + 18 V DC Input Voltage Vin - 0.5 to VDD + 0.5 V DC Output Voltage Vout - 0.5 to VDD + 0.5 V DC Input Current, per Pin I ± in 10 mA DC Output Current, per Pin I ± out 10 mA Power Dissipation, per Package PD 500 mW Storage Temperature Tstg - 65 to + 150 °C Lead Temperature, 1 mm from Case for 10 Seconds TL 260 °C * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the limits in the Electrical Characteristics tables or Pin Descriptions section. This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD.
