Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings are conditions for which the device is
intended to be functional, but device parameter specifications may not be guaranteed. For guaranteed specifications and test conditions, see “Electrical
Characteristics”.
Note 2: As long as TA ≤ +85˚C, all electrical characteristics hold true and the junction temperature should remain below +120˚C except for the 5V output option.
The 5V option requires that TA ≤ +60˚C.
Note 3: The human body model is a 100 pF capacitor discharged through a 1.5 k
Ω resistor into each pin. The machine model is a 200 pF capacitor discharged
directly into each pin.
Note 4: Typical numbers are at 25˚C and represent the most likely norm.
Note 5: All limits guaranteed at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits are 100% tested
or guaranteed through statistical analysis. All limits at temperature extremes are guaranteed by correlation using standard Statistical Quality Control methods (SQC).
All limits are used to calculate Average Outgoing Quality Level (AOQL).
Note 6: The VOUT pin is forced to 200 mV above the typical VOUT. This is to insure that the internal switches are off.
Note 7: The output capacitor COUT is fully discharged before measurement.
