Product Introduction

The SN74LS248 is a BCD-to-Seven-Segment Decoder / Driver(internal pull-up outputs), driver common cathode 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.At the same time, the input and output of the chip are completely compatible with TTL and DTL input and output levels.
