7 segment decoder - SN74LS47N 12VDC ● Support image zoomSN74LS47N is a BCD 7 segment digital tube decoder driver. The function of SN74LS47N is used to convert the BCD code into a number in a digital block. After decoding, the number can be directly converted into a digital tube display number, thereby simplifying the program. This saves the IO overhead of the microcontroller. So it is a very good chip. Specification: Blanking input ripple blanking output and ripple blanking input High sink current outputs
