Texas Instruments  LM293AD

The LM393B and LM2903B devices are the next generation versions of the industry-standardLM393 and LM2903 comparator family. These next generation devices provide outstanding value forcost-sensitive applications, with features including lower offset voltage, higher supply voltagecapability, lower supply current, lower input bias current, lower propagation delay, and improved2kV ESD performance with 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 also ispossible 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.Current drain is independent of the supply voltage. The outputs can be connected to otheropen-collector outputs to achieve wired-AND relationships.
