MotorolaLM 339N

The Motorola LM339N Quad Voltage Comparator 2-36V Open Collector DIP-14 is a low-power quad voltage comparator with open-collector outputs for single- or dual-supply operation.

Technical description

The LM339 contains four independent comparators and operates from 2-36V or +/-1 to +/-18V. The input common-mode range includes ground and the open-collector outputs allow interfacing to different logic families using suitable pull-up resistors.

Indicative applications

Suitable for threshold detectors, zero-crossing, level sensing, oscillators, alarms, power monitoring and interface circuits.

Compatibility note

The outputs are open collector and require external pull-up resistors. It is not intended as a linear feedback operational amplifier.
