The LM393B and LM2903B devices are the next generation versions of the industry-standard LM393 and LM2903 comparator family. These next generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, lower propagation delay, and improved 2 kV ESD performance and input ruggedness through dedicated ESD clamps. The LM393B and LM2903B can drop-in replace the LM293, LM393 and LM2903, for both "A" and "V" grades. All devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Quiescent current is independent of the supply voltage.

The Universal Standard family LM393 / LM339/ LM2903 / LM2901 monolithic ICs integrate two/four independent comparators on a single chip and feature high gain, low power consumption, and an operating voltage range from 2[V] to 36[V] (single power supply). 1) Operating temperature range Commercial Grade LM339/393 family : 0[℃] to 70[℃] Extended Industrial Grade LM2903/2901 family : -40[℃] to 125[℃] 2) Open collector output 3) Single / dual power supply compatible 4) Low supply current 0.8[mA] typ.
