3 Description

The LM393B and LM2903B devices are the next

generation versions of the industry-standard LM393

and

LM2903

comparator

family.

These

next

generation 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 2kV ESD performance with

drop-in replacement convenience.

All devices consist of two independent voltage

comparators that are designed to operate from a

single power supply over a wide range of voltages.

Operation from dual supplies is also possible as long

as the difference between the two supplies is within 2

than the input common-mode voltage. Quiescent

current is independent of the supply voltage, and the

outputs can be connected to other open-collector

outputs to achieve wired-AND relationships.
