LM239A Series Comparators are 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 designed for level detection, low‑level sensing and memory applications in automotive and industrial electronics. They operate from single or split supplies and are TTL and CMOS compatible, with low input bias and offset currents.
The datasheet lists maximum ratings, electrical characteristics such as input bias current (25 nA typ), input offset voltage (1 mV typ), output saturation voltage (130 mV typ at 4 mA), and package dimensions for both N‑suffix (case 646‑06) and D‑suffix (case 751A‑03) devices. Application notes recommend using input resistors under 10 kΩ to prevent oscillation.
