    SN74LS47N Ver 1.00 SN74LS47N ■ Product Introduction The SN74LS47N is a seven segment digital tube decoder / driver with low output efficiency (common anode digital tube). The decoding of BCD code into digital segment code can directly drive the display of digital tube, thus simplifying the program and saving the number of I/O of MCU. The chip is equipped with zero-extinguishing input and output control (RBI and RBO) circuit, digital tube quality detection control (LT) circuit and light-extinguishing control (BI) circuit. One control port (BI/RBO) is shared by the extinguishing lamp and the extinguishing output control, which can be used together to realize the extinguishing control of multi-digit digital display.
