TI LM393BIDSGR

The LM393B and LM2903B devices are the next-generation versions of the industry-standard LM393 and LM2903 comparator families. The next-generation B-version comparators feature lower offset voltage, higher supply voltage capability, lower supply current, lower input bias current, and lower propagation delay, and offer improved 2kV ESD performance and input ruggedness through dedicated ESD clamps. The LM393B and LM2903B are direct replacements for the LM293, LM393, and LM2903 ("A" and "V" versions). All devices contain two independent voltage comparators that can operate from a single supply over a wide voltage range. The quiescent current is independent of the supply voltage.
