Where to use CD4020 IC?
The IC CD4026 is a 14-bit Binary Counter IC from Texas Instruments. It has 12 output pins ranging from Q1 to Q14 excluding Q2 and Q3. When an Input clock pulse is given to the pin for each pulse the binary value gets incremented from 00 0000 0000 0000 to 11 1111 1111 1111 which is equivalent for 0 to 16383 in decimal.
This behavior of the IC can be used to build counters and Dividers, also it is very commonly used for timing related applications. So if you are looking for a 14-bit binary counter which can be incremented through a clock pulse then this IC might be of interest to you.
Applications
- Used for creating long timing period
- Astable frequency divider or counter circuit
- Timing related applications
- Used in project where Microcontrollers should be avoided
