Major Brands LM311N Single Comparator, -15 Volt, 30 Volt, 8-Pin, Plastic Dip Rail, 3.44 mm H x 6.6 mm W x 10.16 mm L (Pack of 15)

Model: LM311N   |    Mpn: LM311N   |    PartNumber: LM311N   |   Asin: B06VWNHFJC

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.

Texas Instruments LM393P LM393 Dual Differential Comparators DIP-8 Breadboard-Friendly (Pack of 5)

Model: LM393P   |    Mpn: LM393P   |    Ean: 0719417815816   |    PartNumber: LM393P   |   Asin: B07PF1Q4XF

The LM393P consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships. The LM393P devices are characterized for operation from 0 C to 70 C.
