Description

The SN54LS47N / 74LS47 are Low Power Schottky BCD to 7-Segment Decoder / Drivers consisting of NAND gates, input buffers and seven AND-OR-INVERTgates. They offer active LOW, high sink current outputs for driving indicators directly. Seven NAND gates and one driver are connected in pairs tomake BCD data and its complement available to the seven decoding AND-OR-INVERT gates. The remaining NAND gate and three input buffers providelamp test, blanking input/ripple-blanking output and ripple-blanking input.
