Basic Logic gates using discrete components Model no. ME 680
Objective :
To verify the truth table for AND gate, OR gate, NOT gate, NAND gate & NOR gate

Features :
Circuit diagram has been printed for 'OR', 'AND' & 'NOT' gates and components mounted on copper sheet front panel and soldered in the back side to demonstrate the working of DTL gates. NAND & NOR gates can be assembled with the combination of OR, AND & NOT gates. Also provided 2 sockets for logic '1' and 2 sockets for logic '0', one red LED for output indicator, 5V DC regulated power supply for logic '1' and logic '0' and 4 patch cords for interconnections.

In logic '1' and logic '0', 2 Red LED output indicators, circuit diagram printed for 'OR', 'AND', EX-OR & 'NOT' gates. NOR gate, NAND gate & Demorgan's Theorems can be connected with the combination of OR, AND & NOT gates.

Input indicators, Circuit diagram for IC 7490 engraved & connections for various inputs & outputs brought on the sockets, patch cords and instruction manual.
