Overview
The Texas Instruments CD40147BE is a 10-input priority encoder designed to convert a decimal input into a binary-coded decimal (BCD) output. Its key operational characteristic is its ability to prioritize multiple active inputs, ensuring only the highest-priority signal is encoded. A critical design consideration when implementing this device is managing the propagation delay, which at 400 ns, can impact the real-time responsiveness of systems requiring very fast state transitions, especially when cascaded.
Key Features
- 10 Input Lines, 4 Output Lines
- Priority Encoder Logic Type
- Operating Supply Voltage: 3 V to 18 V
- Maximum Clock Frequency: 8 MHz
- Propagation Delay Time: 400 ns
- PDIP-16 Through Hole Package (19.3 mm x 6.35 mm x 4.57 mm)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Keyboard encoding for embedded control panels
- Input multiplexing for microcontroller peripheral selection
- Priority interrupt handling in industrial automation
- Digit selection in simple digital display interfaces
