آی سی 74LS47 دیکدر BCD به سون سگمنت

The 74LS47 IC features active low outputs designed for driving common – anode LEDs or incandescent indicators directly. 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).
