TEXAS INSTRUMENTS - LM393DR - IC, DIFFERENTIAL COMP, DUAL, 0.3µS SOIC8
by Kenny Lee Attention electronics Description
The LM393DR is a dual differential comparator. It 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 LM393DR is characterized for operation from 0℃ to 70℃.
