The LM139J from Texas Instruments is a quad differential comparator in a CDIP-14 package rated for the full military temperature range of -55°C to +125°C. It consists of four independent precision voltage comparators designed to operate from a single power supply over a wide range of 2V to 36V, featuring low power consumption, open-collector outputs, and input common-mode range that includes ground.
