Texas Instruments LM339DR

The LM339B and LM2901B devices are thenext generation versions of the industry-standardLM339 and LM2901 comparator family. These nextgeneration B-version comparators feature lower offsetvoltage, higher supply voltage capability, lower supplycurrent, lower input bias current, lower propagationdelay, and improved 2 kV ESD performance andinput ruggedness through dedicated ESD clamps.The LM339B and LM2901B can drop-in replace theLM239, LM339 and LM2901, for both "A" and "V"grades.
