Two Input Nand Gate

Logic Gates Trainer has been designed to study logic gates and applications. This trainer board is designed to verify the truth table of various logic functions, to prove De-Morgan’s theorem, Half adder and Full adder by using logic gates. The board is absolutely self-contained and requires no additional apparatus. 12 V / 1 A DC adaptor is required to operate it.

To study the NOR digital logic gate and verification of the truth table.

This Trainer Consist of : 1. Regulated power supply of ± 12 V / 250 mA. 2. Variable 0 to ±5 V / 250 mA. 3. Sine wave oscillation of 1 KHz. 4. Digital Voltmeter of 0-20 V DC, LCD display, 3 ½ Digit. 5. Functional diagram of IC 741 is printed with 2 mm sockets. 6. One extra 8 pin IC Base with 2 mm sockets. 7. Potentiometer of 10K Ohms. 8. Required Resistance and Capacitances mounted on board. 9. Interconnection Leads and Manual to perform 15 experiments on IC741 e.g. inverting, non-inverting, summing, difference, multiplier, differentiator, integrator etc.

A common anode seven segment module is fitted on a board with 8 bit dip switch to control the each segment of seven segment LED display. The inputs A-D of a display driver are connected to the binary coded decimal (BCD) outputs from a decade counter. A network of logic gates inside the display driver makes its outputs a-g become high or low as appropriate to light the required segments a-g of a seven segment display. A resistor is required in series with each segment to protect the LEDs
