LM239AD Texas Instruments, Quad Comparator, CMOS/TTL/OC O/P, O/P, 1.3μs 36 V 14-Pin SOIC

The Texas offers a LM series of devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide
range of voltages. It provides operation from dual supplies also possible, as long as the difference between the two supplies is 2 V to 36 V.

Low supply current drain independent of supply voltage
Common mode input voltage range includes ground
Low output saturation voltage
