(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not ensured. For specifications, see the Electrical Characteristics tables.
(2) Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under conditions of internal self heating where TJ > TA. See Thermal Information for information on temperature de-rating of this device. Min/Max ratings are based on product testing, characterization and simulation. Individual parameters are tested as noted.
(3) The maximum output current (IOUT) is determined by the device power dissipation limitations (The junction temperature cannot be allowed to exceed 150°C). See Power Dissipation for more details. A short circuit condition should be limited to 5 seconds or less.
(4) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical Quality Control (SQC) methods.
(5) Parameter ensured by design.
(6) Positive Value is current into device.
(7) Slew Rate is the average of the rising and falling edges.
(8) Typical numbers are the most likely parametric norm.
(9) Drift determined by dividing the change in parameter at temperature extremes by the total temperature change.
