ESD Tolerance (2) 2 kV Differential Input Voltage V+ +0.3V, V− −0.3V Voltage at Input V+ +0.3V, V− −0.3V Voltage at Output Pin 15V Supply Voltage (V+–V−) 16V Current at Input Pin (3) ±5 mA Current at Output Pin(4) (5) ±30 mA Current at Power Supply Pin 40 mA Lead Temperature (soldering, 10 sec.) 260°C Junction Temperature (6) 150°C (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For ensured specifications and the test conditions, see the Electrical Characteristics. (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). (3) All limits are specified by testing or statistical analysis. (4) Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C. Output currents in excess of ±30 mA may adversely affect reliability. (5) Limiting input pin current is only necessary for input voltages which exceed the absolute maximum input voltage rating. (6) 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.
