Texas Instruments  LM393DRG3

The LM393B and LM2903B devices are the next generation versions of the industry-standardLM393 and LM2903 comparator family. These next generation comparators provide outstanding value forcost-sensitive applications featuring lower offset voltage, higher supply voltage capability, lowersupply current, lower input bias current, lower propagation delay, and improved 2kV ESD performancewith drop-in replacement convenience.

All devices consist of two independent voltage comparators that are designed to operatefrom a single power supply over a wide range of voltages. Operation from dual supplies is alsopossible as long as the difference between the two supplies is within 2 V to 36 V, andVCC is at least 1.5 V more positive than the input common-mode voltage.Quiescent current is independent of the supply voltage, and the outputs can be connected to otheropen-collector outputs to achieve wired-AND relationships.
