BE Datasheet catalog

dqtasheet We are factory specialized in making LED 7-segment display, dot-matrix display, light bar display and abnormity digital display. So it simply stores latches or stores the data without transferring to a device.

Your shopping bag is empty. See the example below. These 4 data pins are fed binary values.

How to Build a 4511 BCD to 7 Segment Decoder Circuit

This chip saves us a datassheet of work for that reason. Connecting a pin to ground or 0V puts the pin in a LOW state or value.

Each IC takes a binary number as an input, then outputs the necessary lines to display that number on the 7 segment display. If the voltage is too high or the resistor too low think of the datssheet being a resistorthe current going through the LED will exceed the maximum forward current and burn out the LED. We can choose what digit we want to display by inputting the equivalent binary value into these data pins.


Each segment is identified by a letter as can be seen below as well as the pinout and schematic for reference. The decimal equivalent of the binary value that it holds will be displayed on the 7 segment display. This provides a little over 5ma for each segment. It’s simply to test all the outputs to check if they turn on. Every LED has a maximum forward current and forward voltage.

With the binary value input, the equivalent decimal value dtasheet that binary number is displayed on the 7 segment display. Without the pushbuttons being pressed, the pins are all in a LOW state. So if we want to show a 4, we pressed down on pushbutton C while having all the other pushbuttons unpressed. When LOW, this feature is not activated.

How to Build a BCD to 7 Segment Decoder Circuit

This is because we want to strobe the outputs to the 7 segment LED display. The binary value is the equivalent of the decimal value of 6.


In this circuit, we will build a BCD to 7 segment display decoder circuit using the chip. Since this is being powered by a 9V battery, Datadheet am using 1.

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

We can show the digits 0 through 9. Being that dafasheet don’t wish to use this feature, we simply connect it permanently HIGH. This means that the negative side of all the LEDs are connected together. In this example I will be using 2 x and 2 x 7 segment module. Using the 7 segments, you can make any decimal digit.

This pin is active LOW. However, if you do want to use this feature, you can simply connect it to a pull-up resistor with a pushbutton.

There are 4 data pins hold a binary value. When pressed, it will go LOW and turn off all 44511be outputs. This calculator will help you figure out the resistor size http: The chip is capable of handling up to 20V. Remember Me Lost your password?
