Description

74LS47 BCD – 7 segment Decoder IC

74LS47 is a Low Power Schottky BCD to 7-Segment Decoder/Driver consisting of NAND gates, input buffers and 7 AND-OR-INVERT gates. They offer direct active low, high sink current outputs for driving indicators. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven AND-OR-INVERT gates.
