General Description
The 74LS47 accepts four lines of BCD input data, generates their complements internally and decodes the data with secen AND/OR gates having open-collector outputs to drive indicator segments directly. Each segment output is guaranteed to sink 24mA in ON (low) state and withstand 15V in the OFF (high) state with a maximum leakage curent of 250uA. Auxiliary inputs provided blanking, lamp test and cascadable zero-suppression functions.
