7447 or 74LS47 decodes BCD into 7 Segments, means it accepts a binary coded decimal or BCD Values as input and decoded into a pattern that drives a 7-segment for displaying digits 0 to 9, so its name is BCD to 7 segment driver or decoder. Its input is 4 lines BCD data and generates complements as output. The generation of complement data of BCD is internally so no coding or programming is required to generate it.
