Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device

is intended to be functional. For guaranteed specifications and test conditions, see the Electrical Characteristics.

Note 2: The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.

Note 3: For detailed information on soldering the plastic TSSOP package, refer to the Packaging Databook available from National Semiconductor.

Note 4: Minimum and Maximum limits are guaranteed through test, design, or statistical correlation using Statistical Quality Control (SQC) methods. Typical values

Level (AOQL).

Note 5: Device thermal limitations may limit usable range.

Note 7: During rear auxiliary operation, the RTN pin can be approximately -0.4V with respect to VEE. This is caused by normal internal bias currents, and will not

harm the device. Application of external voltage or current must not cause the absolute maximum rating to be exceeded.
