Note 1 Absolute maximum ratings indicate limits beyond which damage to the component may occur Electrical specifications do not apply when operating the
device 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 Shorting an Output to V
V
If the total power from all shorted outputs causes the junction temperature to exceed 150 C degraded reliability or destruction of the device may occur To
determine junction temperature see Note 5
Note 5 Junction temperature may be calculated using T
packages soldered to copper-clad board with dissipation from one comparator or reference output transistor nominal i
Note 6 Human body model 100 pF discharge through a 1 5 kX resistor
Note 7 Typical values in standard typeface are for T
most likely parametric norm
Note 8 All limits are guaranteed for T

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
10
parameter is guaranteed by design and sample testing
Note 11 Hysteresis is the change in V
hysteresis to the typical value its junction temperature should be cycled in the following pattern spiraling in toward 25 C 25 C 85 C
Note 12 Low contact resistance is required for accurate measurement
Note 13 A military RETS electrical test specification is available on request The LM615AMJ 883 may also be procured as a Standard Military Drawing
