† 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.

‡ Unless otherwise specified all voltages are with respect to Ground. Currents are positive into, negative out of the specified terminal. Consult

Packaging Section of Unitrode Integrated Circuits databook for thermal limitations and considerations of packages.
