Use four such switches to control four of the seven segments.

MAN72A PDF डेटा पत्रक – (MANxxA) 7 Segment Display

We will use the MAN72A or equivalent seven-segment display. Draw a diagram of your entire circuit. Do not connect any segment directly to 5 V, or you will destroy the LED within datashdet segment.

Build your circuit and demonstrate that all values zero to nine are represented correctly as a decimal digit on your seven-segment display. Use them so that the most significant bit of the four-bit binary number is on the left side.


Show an instructor your switching circuit. You will find a one-page diagram of the internal connections of these eight chips on the 29A web datasheeet.

We recommend you use any or all of the following logic chips: The four-bit binary number has value zero to fifteen, but we are going to display only numbers zero to nine, with digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In this lab you will build a circuit that presents a four-bit binary value as a single decimal digit on a seven-segment display. The drawing below shows how the LEDs of the seven segments are connected to the fourteen pins of the package.

Use four logic switches on your breadboard as input to your circuit.

Choose logic gates to implement your logic equations. Your instructors will help you understand what you are supposed to do, but your datasjeet is to design, build, and correct the circuit yourself. For each segment in the display, make a Karnaugh map that relates the four bits of the number to the state of the segment, so that the segment will illuminate correctly to display the value of jan72a number as a decimal digit.


Use your Karnaugh maps to obtain efficient boolean equations to implement the seven-segment logic. Show an instructor your work. You have switches on your breadboard to supply 0 V and 5 V.

Figure out how you are going to switch on and off individual segments of this display with 5-V logic levels. All of them come in a pin DIP package. The construction itself is a challenge, because of the large number of gates you must connect together correctly.
