LM339 Datasheet, PDF (1/6 Pages) Motorola, Inc – Quad Single Supply Comparators

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 ent drain is independent of the magnitude of the power supply voltage. The
outputs can be connected to other open - collector outputs to achieve wired -AND relationships.
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
