Highly Flexible Voltage
Comparators
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 VCC or the VEE 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.
