This is why it’s called binary coded decimal. For example, if we want to display 6 on the 7 segment display, we input the value into the DBCA data pins. Already have an account? BCD code for both type of display common-cathode and common-anode given in the table below:. This mode is the mode we usually want it in for display purposes. This pin would turn on all the outputs if connected LOW.

Displsy this example I will be using 2 x and 2 x 7 segment module. Log in or register to post Comment. The chip takes in a binary value and displays the equivalent decimal value on the 7 segment display. These are the pins we attach to each of the corresponding pins on the 7 segment LED display.

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

However, if you do want to use this feature, you can simply connect it to a pull-up resistor with a pushbutton. This mode is the mode we usually want it in for display purposes.

Write Your Own Review You’re reviewing: It has sufficient output current to directly drive a seven segment display. Same Day Dispatch Orders placed online before 3: So for getting any particular decimal number you just follow the table and you will get to know that out of 4 which buttons you have to press for displaying the particular number.


Max output current per pin: IC has some inputs pins called BCD.

View all related questions. BCD code for IC These data pins are referred to in the datasheet as D, B, C, and A.

BCD to 7 Segment Converter (4511B)

This is how we adjust the value of these data pins. When HIGH, the lamp test is activated.

In this circuit, we will start the BCD to 7 segment display decoder with the most basic fo. And all the positive terminals are left alone. Already have an account?

BCD to 7 Segment Converter (B)

Common cathode h g f e d c b a. How the BCD to 7 segment display decoder works is it has vcd pins that intake a binary value. This calculator will help you figure out the resistor size http: Click here to download operating information for this part. Being that we don’t want the blanking feature activated, we simply connect it permanently to HIGH.


This IC is used where we need to driving common-cathode displays like 7-segment display, low voltage fluorescent display, and incandescent display. The 4 input data pins, which control the digit which is shown on the 7-segment LED display, are D, C, B, sisplay A which are pins 6, 2, 1, and 7, respectively. The binary value is the equivalent of the decimal value of 6. UK Deliveries If you live on the UK mainland and don’t have any large materials or lithium batteries in your order it will cost 3.
