Electrical Characteristics
Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the de-
vice beyond its rated operating conditions.
Note 2: Input voltage above V
Note 3: More accurately, it is excessive current flow, with resulting excess heating, that limits the voltages on all pins. When any pin is pulled a diode drop below
V
and unpredictable when any parasitic diode or transistor is conducting.
Note 4: Junction temperature may be calculated using T
soldered to copper-clad board with dissipation from one comparator or reference output transistor, nominal
Note 5: Human body model, 100 pF discharged through a 1.5 k
Note 6: Typical values in standard typeface are for T
most likely parametric norm.
Note 7: All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold type face).
Note 8: Slew rate is measured with op amp in a voltage follower configuration. For rising slew rate, the input voltage is driven from 5V to 25V, and the output voltage
transition is sampled at 10V and
Note 9: V
Note 10: Average reference drift is calculated from the measurement of the reference voltage at 25˚C and at the temperature extremes. The drift, in ppm/˚C, is

is guaranteed by design and sample testing.
Note 11: Hysteresis is the change in V
hysteresis to the typical value, cycle its junction temperature in the following pattern, spiraling in toward 25˚C: 25˚C, 85˚C, −40˚C, 70˚C, 0˚C, 25˚C.
Note 12: Low contact resistance is required for accurate measurement.
Note 13: A military RETSLM614AMX electrical test specification is available on request. The LM614AMJ/883 can also be procured as a Standard Military Drawing.
