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.
