Tổng quan

Description

The SI8642ED-B-ISR is a dual-channel digital isolator from Silicon Labs, designed for high-speed, noise-immune signal transmission across isolated circuits.
### Key Features:
- Isolation: 5 kVrms reinforced isolation (UL/IEC 60747-17 certified).
- Channels: 2 bidirectional channels (supports unidirectional use).
- Speed: Up to 150 Mbps data rate.
- Power: Low power consumption (1.5 mA/channel typical).
- Voltage Range: 2.5V to 5.5V supply on both sides.
- Package: 16-pin SOIC (wide-body).
### Applications:
- Industrial automation (PLC, motor control).
- Medical equipment.
- Isolated communication interfaces (SPI, I²C).
### Advantages:
- High noise immunity (CMTI: ±50 kV/µs).
- Robust isolation with long-term reliability.
- AEC-Q100 qualified for automotive use.
The SI8642ED-B-ISR is ideal for applications requiring reliable, high-speed isolation with minimal power consumption.
