MOTOROLA ANALOG IC DEVICE DATA
The ability to operate from a single power supply of 5.0 V to 30 V or ±15 V
split supplies, as commonly used 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. Thus the LM211/LM311 can be used to
drive relays, lamps or solenoids.

NOTES: 1. Offset voltage, offset current and bias current specifications apply for a supply voltage range from a single 5.0 V supply up to ±15 V 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 offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1.0 mA load. Thus,
these parameters define an error band and take into account the ”worst case” effects of voltage gain and input impedance.
4. The response 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.
