Multiplexer - Demultiplexer 8:1 and 1:8 Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12764
Indian Lab Suppliers supplies the Multiplexer - Demultiplexer 8:1 and 1:8 (Product ID: 12764) as part of its electronics engineering lab equipment range. It verifies the truth tables of an 8-to-1 line multiplexer (74151) and a 1-to-8 line demultiplexer (74138).
Quick Answer
The 74151 selects one of eight data inputs using three select lines, and the 74138, used as a demultiplexer, routes one input to one of eight outputs chosen by three address lines. Eleven SPDT switches set the eight data inputs and three select lines, and eight LEDs show the output states. A 5 V DC, 100 mA regulated supply is built in; the board runs from 230 V ±10%, 50 Hz mains, weighs about 2 kg and measures W 415 × H 165 × D 315 mm.
