BCD to 7-Segment Decoder/Driver with Open-Collector Outputs
DM74LS47 BCD to 7-Segment Decoder/Driver with Open-Collector Outputs October 1988 Revised March 2000 DM74LS47 BCD to 7-Segment Decoder/Driver with Open-Collector Outputs General Description Features The DM74LS47 accepts four lines of BCD (8421) input � Open-collector outputs data, generates their complements internally and decodes � Drive indicator segments directly the data with seven AND/OR gates having open-collector � Cascadable zero-suppression capability outputs to drive indicator segments directly. Each segment � Lamp test input output is guaranteed to sink 24 mA in the ON (LOW) state and withstand 15V in the OFF (HIGH) state with a maxi- mum leakage current of 250 μA. Auxiliary inputs provided blanking, lamp test and cascadable zero-suppression func- tions.
