LM339
Description
The LM339 consists of four independent voltage comparators. These were designed specifically to operate
from a single power supply over a wide range of voltages. Operation from split power supplies is also possible
and the low power supply curr
outputs can be connected to other open
Features
§
Wide supply voltage range
Low supply current drain independent of supply voltage.
§
Low input biasing current
§
§
Low input offset current
Low input offset voltage
§
§
Input common- mode voltage range includes GND
§
Differential input voltage range equal to the power supply voltage
§
Low output saturation voltage
§
Output voltage compatible with TTL, MOS and CMOS logic
ent drain is independent of the magnitude of the power supply voltage. The
collector outputs to achieve wired
- -AND relationships.
