Overview
The Broadcom Limited HCPL-263A is a high-speed, dual-channel logic output optoisolator designed for robust digital signal isolation. Its primary function is to provide galvanic separation between a low-voltage control circuit and a higher-voltage or noisy system, crucial for preventing ground loops and protecting sensitive components. A key design consideration is the trade-off between its 10MBd data rate and the 100ns maximum propagation delay; achieving higher speeds often necessitates careful layout to minimize parasitic capacitance and ensure signal integrity, especially in noise-sensitive applications.
Key Features
- Isolation Voltage: 3750Vrms
- Data Rate: 10MBd
- Common Mode Transient Immunity (CMTI): 1kV/µs (minimum)
- Output Type: Open Collector, Schottky Clamped
- Propagation Delay (Max): 100ns
- Package: 8-DIP (0.300″ width)
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.
- High-speed digital interface isolation in industrial control systems
- Power supply control and monitoring circuits
- Interfacing microcontrollers to high-voltage gate drive signals
- Noise reduction in sensitive measurement equipment
