Si8641BB-B-IS1 Digital Isolator
150 Mbps High-Speed Data meets 2.5 kV RMS Isolation – The Professional Quad-Channel Digital Isolator Silicon Choice for High-Density Industrial Bus Telemetry.
// Ultra-Low Power Core 3 Forward / 1 Reverse Channel Symmetrical 16-Pin SOIC Portfolio
The High-Speed Low-Latency Data Isolation Advantage
The Si8641BB-B-IS1 represents a premier professional quad-channel digital galvanic isolator solution engineered for space-constrained, high-speed hardware architectures demanding absolute signal processing efficiency and robust noise immunity profiles. Utilizing Skyworks’ proprietary capacitive isolation technology, this module processes up to 150Mbps high-frequency data transmission across 3 forward and 1 reverse directional channels flawlessly without propagation jitter or latch-up hazards. Housed in a standard 16-pin SOIC Narrow Body package footprint, it secures pure, deterministic digital routing and completely cuts off high-voltage ground loop vulnerabilities.
- High-speed data throughput up to 150 Mbps supporting rapid industrial communication interfaces cleanly
- Robust 2.5 kV RMS galvanic isolation rating shielding sensitive MCUs against power bus transients safely
- Optimized channel configuration layout (3/1 structure) perfectly matching isolated SPI bus architectures smoothly
