Product Overview
Archer Cat. No. 276-1712 houses an LM339N four-channel differential voltage comparator in a standard 14-pin through-hole DIP package. Each of the four independent comparators features an open-collector output that interfaces cleanly with TTL, DTL, MOS, and CMOS logic levels. Operating across single or dual supply rails, it provides dependable threshold detection and level shifting for repairs, legacy hardware maintenance, and analog circuit builds.
Key Features
- Four independent voltage comparators in a single 14-pin DIP package
- Flexible power supply: single rail +2VDC to +36VDC or split supplies ±1VDC to ±18VDC
- Open-collector outputs compatible with TTL, DTL, MOS, and CMOS logic families
- Low supply current drain: 0.8mA typical, independent of supply voltage
- Input common-mode voltage range includes ground
- Through-hole mounting for standard breadboards and DIP sockets
Applications
- Zero-crossing and level detectors in analog sensor circuits
- Window comparator stages for battery voltage monitoring
- Analog threshold triggering for digital microcontroller inputs
- Audio pulse shaping and synthesizer waveform generation on hobby breadboards
Frequently Asked Questions
What logic families are compatible with the outputs?
The open-collector outputs pull down to ground and interface with TTL, DTL, MOS, and CMOS circuits when paired with an external pull-up resistor matched to the logic supply.
Can this comparator run from a single 5V rail?
Yes. The LM339 operates down to +2VDC, making standard +5VDC single-rail supplies fully compatible.
How many comparators are contained in this IC?
Four independent comparator circuits are housed in the single 14-pin DIP package, so one chip handles up to four threshold detection circuits.
Four clean thresholds from the golden era of hobby electronics, ready for the breadboard build that needs genuine period silicon. Drop it into a 14-pin socket and put those open collectors to work.
