Octal to Binary Encoder Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12746
Indian Lab Suppliers supplies the Octal to Binary Encoder (Product ID: 12746) as part of its electronics engineering lab equipment range. It studies the 8-line to 3-line encoder IC 74148, which converts one of eight octal inputs into a 3-bit binary code.
Quick Answer
The 74148 is a priority encoder: when more than one of its eight active-low inputs is asserted, it outputs the code of the highest-numbered one. Nine SPDT switches set the eight data lines and the enable input, and 14 LEDs show input and output status. A 5 V DC, 100 mA regulated supply is built in and the unit runs from 230 V ±10%, 50 Hz mains, with sockets for connections and waveform observation.
