Computer Logic Training Board has been designed specifically for the study of 4 line to 16 line Decoder, 1 to 16 demultiplexer and its application as sequencer. This Training Board gives a better understanding of decoding 4 lines to 16 lines. It also explains the phenomena of Demultiplexing with one input signal and sixteen outputs using four control signals. It gives an idea to sequence among a number of states.
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.

Object:

1. To demonstrate the operation of a 1 line to 16 line demultiplexer.
2. To demonstrate the operation of 4 line to 16 line decoder.
3. To demonstrate how 4 line to 16 line decoder can be used to sequence among any number of states, between one and fifteen. (This is called a programmable sequencer with 4 binary inputs and 16 outputs).

Features:
The board consists of the following built-in parts :

1. 5VD.C. at 200mA, IC regulated power supply internally connected.
2. 1 to 16 Decoder/Demultiplexer IC.
3. LEDs (22 No’s) for visual indication of status.
4. SPDT (6 No’s) switches for logic selection.
5. Adequate no. of other Electronic Components.
6. Mains ON/OFF switch, Fuse and Jewel light.
7. The unit is operative on 230V ±10% at 50Hz A.C. Mains.
8. Good Quality, reliable terminal/sockets are provided at appropriate places on panel for connections/ observation of waveforms.
9. Strongly supported by detailed Operating Instructions, giving details of Object, Theory, Design procedures, Report Suggestions and Book References.
