Product Summary

The LM393 is a dual differential comparator. The LM393 consists 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 LM393 is characterized for operation from 0℃ to 70℃.

Parametrics

LM393 absolute maximum ratings: (1)Supply voltage, VCC: 36 V; (2)Differential input voltage, VID: ±36 V; (3)Input voltage range, VI (either input): –0.3 V to 36 V; (4)Output voltage, VO: 36 V; (5)Output current, IO: 20 mA; (6)Duration of output short-circuit to ground: Unlimited; (7)Package thermal impedance, θJA: 97℃/W; (8)Case temperature for 60 seconds: 260℃; (9)Lead temperature 1,6 mm (1/16 inch) from case for 10 seconds: 260℃; (10)Storage temperature range, Tstg: –65 to 150℃.
