When LOW, the pin is in strobe mode, meaning it strobes the output to a given device, which in this case is aД§ segment LED display. Has dual purposes depending on whether it's HIGH or LOW. The LE/ STROBE pin is the Latch Enable/ STROBE Go LOW, so they'll all shut off, like a reset pin. It's simply to test all the outputs to check if they turn on. This makes all the outputs HIGH, so if LEDs are attached to all of the outputs, all of the LEDs will turn on if this Pin 3 is the LT pin, which is the Lamp Test pin. So, for example, if we want to show the decimal numberДҐ, we give a value of 0101 to the DCBA data pins. Value that it holds will be displayed on the 7 segment display. There are 4 data pins hold a binary value. How we adjust the value of these data pins. Connecting a pin to ground or 0V puts the pin in a LOW state or value. The 4 input data pins, which control the digit which is shown on the 7-segment LED display, areД, C, B, and A which are pins 6, 2, 1, and 7, respectively. The 4511 chip is capable of handling up to 20V. To power the chip, V DD, pin 16 to 5V and V SS, pin 8, connects to ground. The 4511 chip takes in a binary value and displays the equivalent decimal value on the 7 segment display. The 4511 BCD to 7 segment display decoder can be gotten very cheaply for under $1 on ebay. So we can see which combinations of pushbuttons turned onД«elow, we will also explain how BCD to 7 segment display decoders work in great detail, specifically 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 theseДata pins. These data pins are referred to in the datasheetДЄs 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.Д®ach 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 fromД to 9- using only 4 pins. In this circuit, we will build a BCD to 7 segment display decoder circuit using the 4511 chip.ДЄ 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
