Two Input or Gate

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

Each module is housed in a plastic box 90 x 90 x 30 mm and is provided with a circuit diagram on the panel. It has necessary input and output sockets. The socket stacking system allows addition of as many modules as desired, designed to work on 6V D. C.

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

Complete with Regulated power supply of + 5V/500 mA. Provided with 4 Logic input switches (bounceless) 4 LED Indicators (Buffered) Functional diagram of :- 1. 3 Input NAND – 6 No. 2. 4 Input NAND – 4 No. 3. 1 Input NOT Gates – 4 No. is printed on board. 4. 12 Interconnection Leads and User’s Manual is provided.
