description
These 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
2 V to 36 V and V
CC
is at least 1.5 V more positive than the input common-mode voltage. Current drain is
independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve
wired-AND relationships.
The LM193 is characterized for operation from –55°C to 125°C. The LM293 and LM293A are characterized for
operation from –25°C to 85°C. The LM393 and LM393A are characterized for operation from 0°C to 70°C. The
LM2903 and LM2903Q are characterized for operation from –40°C to 125°C and is manufactured to demanding
automotive requirements.
