74LS47 - BCD to 7-Segment Decoder/Driver IC Size:Default Title Bidirectional Logic Level Conversion74LS47 BCD to 7 Segment Decoder Driver IC The 74LS47 accepts four lines of BCD (8421) input data, generates their complements internally and decodes the data with seven AND OR gates having open collector outputs to drive indicator segments directly. Each segment output is guaranteed to sink 24 mA in the ON (LOW) state and withstand 15V in the OFF (HIGH) state with a maximum leakage current of 250 A. Auxiliary inputs provided blanking, lamp test and
