description
These devices consist of two independent voltage
NC – No internal connection
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies also is 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 is characterized for operation from –40°C to 125°C. The LM2903Q is tested from –40°C to 125°C and
is manufactured to demanding automotive requirements.
