LM393 -Low Power Low Offset Voltage Dual Comparator rd50 The presence of dust canThese devices 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
