CD4511 BCD to Seven Segment Driver IC

CD 4511 is a BCD to 7-segment latch decoder driver IC formed with CMOS logic and NPN bipolar transistor output devices on an immovable structure. This IC is used where we need to driving common-cathode displays like 7-segment display, low voltage fluorescent display, and incandescent display. It is having a DC supply input ranges from 3 to 18v with a normal operating temperature range from -40°C to +85°C.

BCD to 7-Segment Decoder Circuit with IC 4511: Initially the display will show Zero, as buttons are connected to pull down resistors and gives LOW as output when no button is pressed. 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. Pressing any button will give a high input to the corresponding pin of 4511 and accordingly decimal number will be displayed on 7-segment. You can show decimal number from 0 to 9 on a single 7-segment display.( Click for wide range of  Logic Gates at

Note : In case of common-anode displays one can refer IC7447 for BCD to 7 segment display (common anode 7 segment display).
