Working Principles

CD40147BEG4 works on the principle of priority encoding. It assigns priority to each input line based on its position, with higher-positioned lines having higher priority. When multiple input lines are active simultaneously, only the highest-priority line is encoded and reflected on the output lines. The enable input (E) controls the encoding process, allowing or inhibiting the generation of the output code.

Detailed Application Field Plans

CD40147BEG4 finds application in various fields where data encoding and decoding are required. Some specific areas of application include:

1. Communication Systems: Used for encoding and decoding data signals in communication protocols.
2. Industrial Automation: Enables efficient data handling in control systems and PLCs.
3. Automotive Electronics: Utilized in vehicle electronics for encoding sensor inputs and decoding control signals.
4. Consumer Electronics: Integrated into devices like remote controls, keypads, and digital displays for data processing.

Detailed and Complete Alternative Models

1. CD40147BE: Similar to CD40147BEG4, but without the "G4" suffix indicating RoHS compliance.
