3 Description

The LM339B and LM2901B devices are the

next generation versions of the industry-standard

LM339 and LM2901 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 LM339B and LM2901B can drop-in replace the

LM239, LM339 and LM2901, for both A and V

grades.

All devices consist of four independent voltage

comparators that are designed to operate from a

single power supply over a wide range of voltages.
