LM339/D is a comparator designed for use in level detection, low-level sensing, and memory applications in consumer automotive and industrial electronic applications.
The LM339 family of quad comparators are single‑supply or split‑supply devices designed for level detection, low‑level sensing and memory applications in consumer, automotive and industrial electronics. They feature low input bias current, low offset voltage, and TTL/CMOS compatible outputs.
The datasheet lists detailed electrical characteristics such as typical input bias current of 25 nA, typical input offset voltage of 1 mV, and output saturation voltage of 130 mV at 4 mA. It also provides maximum ratings, operating temperature ranges, power dissipation limits, and mechanical dimensions for the available DIP‑14 and SO‑14 packages.
| Typical Input Bias Current | 25 nA |
|---|---|
| Typical Input Offset Voltage | 1.0 mV |
| Typical Output Saturation Voltage | 130 mV @ 4.0 mA |
