The LM139J/PB is a quad comparator from Texas Instruments designed for low-power applications. It operates over a wide supply voltage range of 2 to 36 V DC or ¬±1 to ¬±18 V DC, making it versatile for various circuit designs. The device features a low input offset voltage of ¬±3 mV and a low input bias current of 25 nA, which enhances its precision in voltage comparison tasks. The output is compatible with TTL, DTL, ECL, MOS, and CMOS logic systems, allowing for easy integration into digital circuits. This comparator is suitable for applications such as limit comparators, analog-to-digital converters, and pulse generators. It has a maximum quiescent current of 2.5 mA and can drive output currents up to 16 mA at 5 V. The LM139J/PB is packaged in a 14-CDIP format, suitable for through-hole mounting, and is rated for an operating temperature range of -55¬8C to 125¬8C. The product is halogen-free and compliant with environmental standards, making it a reliable choice for engineers looking for a robust comparator solution.
