3 Description
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 provide
outstanding value for cost-sensitive applications
featuring 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, and the outputs can be connected to other
open-collector outputs to achieve wired-AND
relationships.
