74LS47 - BCD to 7-Segment Decoder-Driver

74LS47 - BCD to 7-Segment Decoder-Driver

The 74LS47 accepts four lines of BCD  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.

74LS47 is a BCD to 7-segment decoder/driver IC. It accepts a binary coded decimal as input and converts it into a pattern to drive a seven-segment for displaying digits 0 to 9. Binary coded decimal (BCD) is an encoding in which each digit of a number is represented by its own binary sequence (usually of four bits).

Features:

  • Open-collector outputs
  • Drive indicator segments directly
  • Cascadable zero-suppression capability
  • Lamp test input
