† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

‡ All typical values are at VCC = 5 V, TA = 25°C.

§ The output conditions have been chosen to produce a current that closely approximates one half of the true short-circuit output current, IOS.
