SN74LS47 datasheet


The SN74LS47 are Low Power Schottky BCD to 7-Segment Decoder /Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERT gates. They offer active LOW, high sink current outputs for driving indicators directly. Seven NAND gates and one driver are connected in pairs to make BCD data and its complement available to the seven decoding AND-OR-INVERT gates. The remaining NAND gate and three input buffers provide lamp test, blanking input/ripple-blanking output and ripple-blanking input.


1. Lamp Intensity Modulation Capability (BI/RBO)
2. Open Collector Outputs
3. Lamp Test Provision
4. Leading/Trailing Zero Suppression
5. Input Clamp Diodes Limit High-Speed Termination Effects
