The SN74LS48N is a seven segment digitally controlled decoder / driver that outputs high efficiency (digital tube common cathode). It is used to transform the BCD code into the number in the digital tube, thus simplifying the program and saving the number of MCU I/O. The input and output terminals are fully compatible with TTL and DTL input and output interfaces.
The chip has zero-killing input and output control (RBI and RBO), digital tube quality detection control (LT) and light-out control (BI) functions. 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.
