IC 74147 Pin Diagram, Internal Circuit, Truth Table

IC 74147 is a digital encoder IC that encodes 9 input lines into 4 output lines. It is also known as the Decimal to BCD priority encoder. The priority encoder term is used because it provides encoding for the highest-order data lines as a first priority. It is made up using Transistor-Transistor Logic(TTL) technology. It is a 10 to 4 encoder IC.  In this article, we are going to see IC 74147 Pin Diagram, IC 74147 Internal Circuit Diagram, and IC 74147 Truth table or function table.
