manufacturer part number: LM339DT
The LM339 has 4 separate, on-board voltage comparators, each capable of comparing two analog voltages and outputting a digital signal indicating which input is higher. This is the chip at the heart of many electronic sensors, such as the one found in the "clapper" - or your kid's line-following robot kit.
This is the surface mount version (SMD/SMT) of the LM339 Quad Comparator - in a tiny, but hand-solderable SOIC-14 package.
