LM139DT ST Comparators

The LM139DT is a low-power quad voltage comparator from STMicroelectronics in SO-14 surface-mount package, featuring four independent precision voltage comparators with low offset voltage and low power consumption. For selection, verify single supply from 2V to 36V or dual supplies from ±1V to ±18V, response time, supply current of 0.8mA typical, input offset voltage, open-collector outputs for wired-OR configurations, wide common-mode range including ground, and operating temperature from -55°C to +125°C. Features include low power consumption, high input impedance, differential input voltage range equal to power supply voltage, and TTL/CMOS compatible outputs. Ideal for level detection, zero-crossing detectors, window comparators, oscillator circuits, voltage monitoring, sensor interfaces, and any multi-channel analog comparison requiring quad comparator configuration with extended temperature range.
