• Requires external components for decoding the output

Working Principles

The CD74HC147NSR is a priority encoder that converts 10-line input data into a 4-bit binary output. It uses priority encoding to ensure that only the highest-priority input is encoded. The inputs are compared in descending order of priority, and the first active (logic high) input is encoded into the corresponding binary output.

Detailed Application Field Plans

The CD74HC147NSR can be used in various applications, including:

1. Data transmission systems
2. Communication networks
3. Industrial automation
4. Robotics
5. Security systems
