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.
