Where to use CD4035 IC

The CD4035 has two 4-bit Parallel In – Parallel Out Shift Register. Meaning it can receive (input) data-parallel and control 4 output pins in parallel. This comes in very handy where does not have enough GPIO pins on our MCU/MPU to control the required number of outputs. It is often used in projects where relatively a large number of LEDs have to be controlled through the Microcontroller. It can also be used to interface LCD screens since they can act as the data bit for the LCDs.

Applications of CD4035:

  • Counters, Registers
  • Arithmetic-unit registers
  • Shift-left — shift right registers
  • Serial-to-parallel/parallel-to-serial conversions
  • Sequence generation
  • Control circuits
  • Code conversion
