The ST LM139D is a quad differential comparator IC designed for various electronic applications. It features four independent comparator channels, each with an open-collector and open-drain output configuration, allowing for flexible interfacing with different logic families.
This comparator operates with a supply voltage ranging from 2V to 36V, making it suitable for a broad spectrum of power supply requirements. The device exhibits a typical propagation delay of 1.3 µs and a low typical current consumption of 0.2 mA per channel. The input bias current is specified at a maximum of 25 nA, and the offset voltage at 25°C is a maximum of 5 mV.
The operating temperature range for the LM139D is -55°C to 125°C, ensuring reliable performance in demanding environmental conditions. The common-mode input voltage range includes ground, and the differential input voltage range can extend up to the maximum-rated supply voltage of ±38V. The output saturation voltage is low, and the outputs are compatible with TTL, MOS, and CMOS logic levels.
The LM139D is supplied in a 14-pin SOIC (D) package with an area of 51.9 mm². This package type is suitable for surface mounting applications.
