Overview
The Nexperia HEF4028BT is a BCD-to-Decimal decoder/demultiplexer designed for robust digital signal routing. Its primary function is to convert a 4-bit Binary Coded Decimal (BCD) input into one of ten mutually exclusive decimal outputs, enabling precise control in sequential logic. A critical design consideration when implementing the HEF4028BT is managing the propagation delay, which at 50 ns, can impact the timing margins in high-speed state machines, necessitating careful layout and clock synchronization to prevent metastable conditions.
Key Features
- BCD to 1-of-10 decoding
- CMOS logic family
- 4-bit BCD input, 10-bit decimal output
- 3V to 15V operating supply voltage
- SOIC-16 package (10mm x 4mm x 1.45mm)
- -40°C to +85°C operating temperature range
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.
- BCD to 7-segment display driving in industrial control panels
- Address decoding for memory banks in embedded systems
- Sequencing control for automated test equipment (ATE)
- Demultiplexing control signals in telecommunications infrastructure
