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 in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.

NOTE 1: The algebraic convention, whereby the most negative value is a minimum and the most positive a
maximum, is used in this table. Negative current shall be defined as conventional current flow out of
a device terminal.
NOTE 2: S1 set to B and S2 open provides a nominal output voltage of 5 volts for device types 01 and 02;
12 volts for device types 03 and 04; 15 volts for device types 05, 06.
NOTE 3: R3 and R4 give a nominal output voltage of 12 volts with S1 set to A and S2 closed.
