LM211, LM311Single Comparators
The ability to operate from a single power supply of 5.0 V to 30 V or $15 V split supplies, as commonly ud with operational amplifiers,makes the LM211/LM311 a truly versatile comparator. Moreover, the inputs of the device can be isolated from system ground while the output can drive loads referenced either to ground, the V CC or the V EE supply. This flexibility makes it possible to drive DTL, RTL, TTL, or MOS logic. The output can also switch voltages to 50 V at currents to 50 mA, therefore, the LM211/LM311 can be ud to drive relays,lamps or solenoids.

Maximum ratings applied to the device are individual stress limit values (not normal operating conditions) and are not valid simultaneously. If the limits are exceeded, device functional operation is not implied, damage may occur and reliability may be affected.

1.Offt voltage, offt current and bias current specifications apply for a supply voltage range from a single 5.0 V supply up to ±15V supplies.
2.This rating applies for ±15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
3.The offt voltages and offt currents given are the maximum values required to drive the output within a volt of either supply with a 1.0mA load. Thus, the parameters define an error band and take into account the “worst ca” effects of voltage gain and input impedance.
4.The respon time specified is for a 100 mV input step with
5.0 mV overdrive.
5.Do not short the strobe pin to ground; it should be current driven at 3.0 mA to 5.0 mA.
