ELECTRICAL CHARACTERISTICS
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Applies to short circuits to ground only. A short circuit between
the output and either supply may permanently damage the part when
operated on supplies greater than 10V.
Note 3: The LT1739C is guaranteed to meet specified performance from
0 C to 85 C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at – 40 C. The LT1739I is
guaranteed to meet the extended temperature limits.
Note 4: Thermal resistance varies depending upon the amount of PC board
metal attached to the device and rate of air flow over the device. If the

Note 7: Slew rate is measured at 5V on a 10V output signal while
operating on 12V supplies and 1V on a 3V output signal while
operating on 5V supplies.
Note 8: This parameter of the LT1739CUE/LT1739IUE is 100% tested at
room temperature, but is not tested at –40 C, 0 C or 85 C.
