Functional Features

• Serial-In, Parallel-Out: The CD4034BM allows data to be inputted serially and outputted in parallel.
• 8-Bit Shift Register: It can store and shift 8 bits of data.
• CMOS Technology: The IC is built using CMOS technology, providing low power consumption and high noise immunity.

Advantages and Disadvantages

Advantages

• Low power consumption due to CMOS technology.
• High noise immunity.
• Easy integration into digital circuits.
• Compact DIP package for easy soldering and handling.

Disadvantages

• Limited storage capacity (8 bits).
• Not suitable for applications requiring larger data storage.

Working Principles

The CD4034BM operates based on the principle of sequential data shifting. When a clock pulse is applied to the Clock Input (CP), the data stored in the Serial Data Input (DS) is shifted to the next stage. The Enable Inputs (ENP and ENT) control the loading of data into the shift register. The Parallel Data Outputs (Q0-Q7) provide the stored data in parallel format.

Detailed Application Field Plans

The CD4034BM is commonly used in various applications, including:

1. LED Display Systems: It can be used to control the display of numeric or alphanumeric characters on LED panels.
2. Industrial Automation: The shift register can be employed in industrial automation systems for data storage and transfer.
3. Digital Counters: It finds application in digital counters where sequential counting is required.
4. Data Communication: The IC can be utilized in serial-to-parallel or parallel-to-serial data conversion.
