General Description
The DM74LS47 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 μA. Auxiliary inputs provided blanking, lamp test and cascadable zero-suppression functions.
Features
1. Open-collector outputs
2. Drive indicator segments directly
3. Cascadable zero-suppression capability
4. Lamp test input
