Where to use CD4511 IC?

This IC combines the low quiescent power dissipation and high noise immunity feature of CMOS with NPN bipolar transistor, which is capable of giving output current of 25mA. Mainly this IC is used for lighting up or driving various types of display like 7-segment, low voltage fluorescent display and incandescent display. But this IC is mainly used for driving the 7-segment display..

 

How to use CD4511 IC?

To use this IC, you don’t need too many things to connect, just need a toggle or push button to change the logic over the ICs input pins and pull down resistor with them as shown in the circuit. A resistor pack or few resistor are also needed to connect a 7-segment display. As the setup complete you just have to follow the table to get the required output number.
