• Manufacturer: National Semiconductor Corporation

Electrical Characteristics
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: For detailed information on soldering plastic TSSOP packages, refer to the Packaging Data Book available from National Semiconductor Corporation.
Note 3: All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with T
guaranteed by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
Note 4: Typical specifications represent the most likely parametric norm at 25˚C operation
Note 5: The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.
Specifications with standard typeface are for T
Temperature range. VIN = 48V, VCC1 = VCC2 = 10V externally applied, R
1.5V, unless otherwise stated (Note 3) and (Note 4).
