Product Usage
The CD4021BCN is a CMOS 8-stage static shift register with parallel or serial input/output capabilities. It is often used in various digital circuits due to its versatility and ability to interface effectively with both microcontrollers and other digital systems. Here are some common circuits and applications where the CD4021BCN might be used:
Digital Input Expansion:
Keypad and Button Matrix:
Data Acquisition Systems:
Remote Control Systems:
LED and Display Control:
Gaming Interfaces:
Industrial Control Systems:
Here’s a simple example of how the CD4021BCN might be connected to a microcontroller to read multiple switches:
Required +-----------+
| CD4021 |
Vcc-----------| 16 14 |----- GND
Switch1-------| 15 13 |----- Data Pin 0
Switch2-------| 10 12 |----- Data Pin 1
Switch3-------| 1 11 |----- Data Pin 2
Switch4-------| 2 10 |----- Data Pin 3
Switch5-------| 3 9 |----- Data Pin 4
Switch6-------| 4 8 |----- Data Pin 5
Switch7-------| 5 7 |----- Data Pin 6
Switch8-------| 6 6 |----- Data Pin 7
| 4 5 |-------Clock
| 3 3 |-------Latch/Enable
+-----------+
In this example, the switches are connected to the parallel inputs of the CD4021 (Pins 11–3). The microcontroller can clock in the states of these switches serially using the data output pin (Pin 3) and the clock pin (Pin 10).
The exact wiring and microcontroller code will depend on the specific microcontroller and application needs.
Using the CD4021BCN in such ways can significantly simplify the design and reduce the number of pins needed on your microcontroller, making your circuits more efficient and compact.
