74LS47 Decoder is an integrated circuit that converts the input binary code in BCD format to logic levels that allow to activate common anode 7-segment display where the position of each bar forms the decoded number. The 74LS47 is a 7-segment decoder integrated circuit. A decoder is a device that converts a sequence of binary inputs into a larger output with a smaller number of outputs. The 74LS47 is a 7-segment decoder, which means it has eight inputs and seven outputs. The eight inputs are used to specify a binary number and the seven outputs control the seven segments of a 7 segment display to show the number in decimal format. The 74LS47 is often used in number display systems and device control systems.
It is a circuit for driving lamp buffers or common anode LEDs. It is used to verify the transformation from BCD to binary. Unlike the 74LS48 circuit is for common cathode 7 segment display drive and 74LS47 is for common anode display.
