LM339
LM339 consists four independent voltage comparators. These were designed specifically operate from single power supply over wide range voltages. Operation from split power supplies also possible power supply curr drain independent magnitude power supply voltage. outputs connected other open collector outputs achieve wired -AND relationships.
Wide supply voltage range supply current drain independent supply voltage. input biasing current input offset current input offset voltage Input common-mode voltage range includes Differential input voltage range equal power supply voltage output saturation voltage Output voltage compatible with TTL, CMOS logic
