Driving a 7 segment display with a 4511 BCD to 7 Segment Driver

In this circuit, we will build a BCD to 7 segment display decoder circuit using the chip. These data pins are referred to in the datasheet as D, B, C, and A. The 4 data pins are D, B, C, and A. If you spend between 40 and 48 – You can see the delivery time and cost at the shipping stage, or by using the shipping estimator from within the shipping basket.

Write Your Own Review You’re reviewing: Pin 4 is the Blanking pin. Without the pushbuttons being pressed, the pins are all in a LOW state. We can choose what digit we want to display by inputting the equivalent binary value into these data pins.

CD 7-Segment Driver IC Pinout, Technical Details, Equivalents & Datasheet

The combination of pushbuttons pressed and unpressed determines the decimal digits, according to the binary value. Each segment is identified by a letter as can be seen below as well as the pinout and schematic for reference.


Being that they are all connected to pull-down resistors, they are all initially LOW when unpressed. For a list of postcodes that will be charged the remote location datashset click here. So, for example, if we input into the data pins, we get the number 0.

For example, if we want to display 6 on the 7 segment display, we input the value into the DBCA data pins. Add to Cart Details. With the binary value input, the equivalent decimal value of that binary number is displayed on the 7 segment display.

We can show the digits 0 through 9. This provides a little over 5ma for each segment. The chip takes in a binary value and displays the equivalent decimal value on the 7 segment display. This is why it’s called binary coded decimal. It can drive LEDs and other displays directly. This connection is available on pins 3 and 8. Using the 7 segments, you can make any decimal digit.

Your email address will not be published. The is 4511 pin chip. The equivalent decimal value of the binary value we feed into the data input pins will be shown. We do not charge a packaging or handling fee for this service, and you will receive an email when your order has been processed, you can collect half an hour after receipt of this email.

So, for example, if we want to show the decimal number 5, we give a value of to the DCBA data ddatasheet. International orders can only be shipped to the registered card address.

Breadboards are invaluable for experimenting with electronic circuits. This is just for information.

Click here to download operating information for this part. The following table explains what the pins do: These are the pins we attach to each of the corresponding pins on the 7 segment LED display. The chip is capable of handling up to 20V. Connecting a dattasheet to ground or 0V puts the pin in a LOW state or value.

In this example I will be using 2 x and 2 x catasheet segment module. Rest of the world These orders are sent via UPS, and the cost is dependant on the service you choose at checkout. When unpressed, the pin will be HIGH.
