Computer Logic Training Board on Multiplexer-Demultiplexer has been specifically designed to give students an idea about Multiplexer-Demultiplexer and to study of Multiplexer-Demultiplexer. The output of the Multiplexer-Demultiplexer can be observed with the help of logic level indicators (LEDs), which are provided on the panel. The board is absolutely self contained and requires no other apparatus. Practical experience on this board carries great educative value for Science and Engineering Students.

The board consists of the following built-in parts :
1. +5V D.C. at 100mA, IC regulated power supply.

2. 21 Input Switches for data input.

3. IC For Multiplexing 74150 is provided on board with Combinational Circuit.

4. IC For Demultiplexing 74154 is provided on board with Combinational Circuit.

5. One Not Gate is provided on board using 7404
 6. 16 Output LEDs with driver circuit to observe the output of Multiplexer-Demultiplexer.

7. A Pulser to provide the pulses manually for triggering.

8. Adequate no. of other Electronic Components.
9. Mains ON/OFF switch, Fuse and Jewel light.

  • The unit is operative on 230V ±10% at 50Hz A.C. Mains.
  • Adequate nos. of patch cords stackable from rear both ends 4mm spring loaded plug, length ½ metre
  • Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections / observation of waveforms.
