Being that we don’t want the blanking feature activated, we simply connect it permanently to HIGH. In this circuit, we will build a BCD to 7 segment display cc4511 circuit using the chip.

We will use a DIP switch to turn various segments on and off. This is just for information.

Your name or email address: Do you already have an account? The chip is capable of handling up to 20V. Using the pushbuttons, you can manually see how depending on which pushbuttons we press, how the output changes in response.

Being that they are all connected to pull-down resistors, they are all initially LOW when unpressed. I want to use the 4 bit input of the cd to display 0 through 9 on an led 7 segment display.

For example, if we want to display 6 on the 7 segment display, we input the value into the DBCA data pins. The combination of pushbuttons pressed and unpressed determines the decimal digits, according to the binary value.

Home – IC Supply – Link. The 4 input data pins, which control the digit which is shown on the 7-segment LED display, are D, C, B, and A which are pins 6, 2, 1, and 7, respectively. When pressed down, it datashdet be LOW and turn on all the outputs.

First we need to familiarize ourselves with the 7 segment module. The pinout of the is shown below.

Your email address will not be published. TI does not warrant or represent. Im trying to drive a single 7 segment display but i dont know how.

CD4511 BCD to 7-segment Latch Decoder Driver

Your shopping bag is empty. When low, the display shows the digit corresponding to the value on the data inputs. The table below summarizes the binary input values to the decimal digit shown on the 7 segment display.


Since this is being powered by a 9V battery, I am using 1. No, create an account now. You should now see a 4 on the 7 segment LED display. Now we will build a very simple circuit to drive a single digit.

This dc4511 is active LOW. We can choose what digit we want to display by inputting the equivalent binary value into these data pins. We will connect this chip by itself to pushbuttons. However, if you want to use this feature in your circuit, you simply connect a pull-up resistor to this pin with a pushbutton.

When HIGH, the lamp test is activated.

When HIGH, this feature is not ativated. So in normal operation, it’s held LOW. Remember Me Lost your password? Yes, my password is: Go to the shop. The 4 data pins are D, B, C, and A. Understanding Current-Voltage Curves This article discusses I-V curves for passive components, voltage sources, and current sources.
