LM139J Description

Short technical summary and product information.

The LM139J by Motorola Semiconductor is a quad differential comparator designed for versatile operation. It supports wide single supply voltages from 2V to 36V and dual supplies from ±1V to ±18V. The device maintains a low supply current drain of 0.8 mA (typical), which is independent of the supply voltage.

Key electrical characteristics include a low input bias current of 25 nA (typical) and a low input offset current of 3 nA (typical). The input offset voltage is typically 2 mV. The common-mode input voltage range includes ground, and the differential input voltage range can equal the maximum-rated supply voltage of ±36V. The output is compatible with TTL, MOS, and CMOS logic systems.

This comparator operates across a wide temperature range of -55°C to 125°C. It is available in multiple package types including CDIP, LCCC, CFP, and SOIC. The standard package quantity is 25 units in a tube. Its robust specifications make it suitable for applications such as power supervision, oscillators, peak detectors, and logic voltage translation in industrial and automotive environments.
