Comparator Single ±15 Volt 30 Volt 8-Pin Plastic Dip Rail
The ability to operate from a single power supply of 5.0V to 30V or ±15V split supplies, as commonly used with operational amplifiers, makes the 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 50V at currents to 50mA, therefore, the LM311 can be used to drive relays, lamps, or solenoids.
