Pushbuttons we press, how the output changes in response.

Using the pushbuttons, you can manually see how depending on which

We will connect this chip by itself to pushbuttons. In this circuit, we will start the 4511 BCD to 7 segment display decoder with the most basic circuit. This chip saves us a lot of work for that reason. Otherwise, you would have to know which pins on the 7 segment display to turn on or off, making it much more complicated. With the binary value input, the equivalent decimal value of that binary number is displayed on the 7 segment display. This is why it's called binary coded decimal. The binary value 0110 is the equivalent of the decimal value of 6. For example, if we want to display 6 on the 7 segment display, we input the value 0110 into the DBCA data We can choose what digit we want to display by inputting the equivalent binary value into theseĭata pins. These data pins are referred to in the datasheetĪs D, B, C, and A. How the 4511 BCD to 7 segment display decoder works is it has 4 pins that intake a binary value.Įach of these 4 pins can hold a 0 (LOW) or a 1 (HIGH). Otherwise, without this chip, to display all the decimal digits (0-9), you would have to use Using binary coded decimal (BCD), we can display any numerical digit on the 7 segment display fromĠ to 9- using only 4 pins. In this circuit, we will build a BCD to 7 segment display decoder circuit using the 4511 chip.Ī BCD to 7 segment decoder circuit is a circuit that intakes a binary value and displays the equivalent How to Build a 4511 BCD to 7 Segment Decoder Circuit
