Note 12: “Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits.”
±
Note 13: This rating applies for 15V supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to the
negative supply voltage or 30V below the positive supply, whichever is less.
Note 14: The maximum junction temperature of the LM311 is 110˚C. For operating at elevated temperature, devices in the H08 package must be derated based
on a thermal resistance of 165˚C/W, junction to ambient, or 20˚C/W, junction to case. The thermal resistance of the dual-in-line package is 100˚C/W, junction to
ambient.

bias current specifications apply for any supply voltage from a single 5V supply up to 15V supplies.
Note 16: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1 mA load. Thus, these
parameters define an error band and take into account the worst-case effects of voltage gain and R .
S
Note 17: The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 18: This specification gives the range of current which must be drawn from the strobe pin to ensure the output is properly disabled. Do not short the strobe
pin to ground; it should be current driven at 3 to 5 mA.
Note 19: Human body model, 1.5 kΩ in series with 100 pF.
