Product details
Overview
SI8463BB-B-IS1R from Skyworks Solutions is a six-channel, ultra-low-power digital isolator in a 16-pin narrow-body SOIC package, supporting up to 150 Mbps data rate with worst-case propagation delay under 9.5 ns, <1.5 ns pulse width distortion, and 0.5 ns channel-to-channel skew - deployed in isolated ADC interfaces and motor control gate drivers.
For engineers reviewing the SI8463BB-B-IS1R datasheet, SI8463BB-B-IS1R pinout, SI8463BB-B-IS1R application, or SI8463BB-B-IS1R equivalent, key selection criteria include its 2.7–5.5 V dual-supply operation, 2500 VRMS reinforced isolation rating, 25 kV/µs common-mode transient immunity, and verified performance at –40 °C to +125 °C across all six channels.
Technical Context
The SI8463BB-B-IS1R implements capacitive isolation with on-chip RF modulation/demodulation circuitry, enabling high-speed signal transmission across galvanically isolated barriers without magnetic coupling or optoelectronic components. It features independent primary-side (VDD1) and secondary-side (VDD2) supplies, each configurable from 2.70 V to 5.5 V.
All six channels operate simultaneously at 150 Mbps with guaranteed timing parameters: ≤9.5 ns max propagation delay, ≤2.5 ns pulse width distortion, ≤3.0 ns propagation delay skew, and ≤1.8 ns channel-to-channel skew. The device achieves 25 kV/µs CMTI and supports 60-year lifetime at rated working voltage per VDE 0884-2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 150 Mbps - enables real-time feedback in servo drives and high-resolution isolated ADC sampling. |
| Propagation Delay | 3.0–9.5 ns (typ/max) - ensures sub-10 ns timing fidelity for synchronous PWM gate drive signals. |
| Isolation Voltage | 2500 VRMS (1 min) - certified for reinforced insulation in industrial inverters and EV battery management systems. |
| Supply Range | VDD1/VDD2 = 2.70–5.5 V - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends. |
| CMTI | ≥25 kV/µs - rejects fast transients in motor phase-leg switching and DC-link noise environments. |
| Channel Count | Six unidirectional channels - supports full three-phase inverter control (6x PWM) or isolated serial interface + status lines. |
| Operating Temp | –40 °C to +125 °C - validated for under-hood automotive and industrial ambient conditions at full speed. |
Pinout & Package
SI8463BB-B-IS1R is housed in a RoHS-compliant 16-pin narrow-body SOIC package (7.5 mm × 10.3 mm, 1.27 mm pitch), with creepage and clearance ≥3.9 mm per IEC 60664-1 and VDE-certified internal insulation structure.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side supply | Power for input-side logic and channel A/B/C drivers; must be decoupled with 0.1 µF ceramic capacitor. |
| GND1 | Primary-side ground | Reference for input signals and VDD1; requires low-inductance connection to PCB ground plane. |
| IN1–IN3 | Input channels 1–3 | Digital inputs referenced to GND1; accept 2.0 V min VIH and 0.8 V max VIL across full temperature range. |
| VDD2 | Secondary-side supply | Power for output-side logic and channel D/E/F drivers; independent of VDD1 for level-shifting capability. |
| GND2 | Secondary-side ground | Reference for output signals and VDD2; galvanically isolated from GND1 by dielectric barrier. |
| OUT1–OUT3 | Output channels 1–3 | CMOS-compatible outputs referenced to GND2; drive 4 mA sink/source with VOH ≥ VDD2–0.4 V. |
| NC | No connect | Pins 8 and 16 are internally unused; must remain unconnected and unbonded per Skyworks design. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power at 100 Mbps | 17.2 mA per side at 2.7 V / 100 Mbps - reduces thermal load in dense power-conversion modules. |
| Sub-10 ns timing precision | ≤9.5 ns max propagation delay + ≤1.8 ns channel skew - preserves edge alignment across all six channels. |
| High CMTI immunity | 25 kV/µs minimum - maintains signal integrity during IGBT/SiC switch turn-on/off transients. |
| No start-up initialization | Valid output within 40 µs of power application - eliminates boot-time delays in safety-critical systems. |
| RoHS-compliant SOIC-16NB | Standard footprint compatible with automated SMT assembly; no lead-free reflow restrictions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM141DARZ | Four-channel, 150 Mbps, 2500 VRMS, SOIC-16 wide-body; higher 10.5 ns max propagation delay. | Limited to four channels; requires two devices for six-signal isolation, increasing BOM count and layout area. | Choose when only four isolated signals needed and wider SOIC footprint acceptable. |
| ISO6763DR | Six-channel, 100 Mbps, 5000 VRMS, SOIC-16 wide-body; lower data rate but higher isolation rating. | Supports higher working voltages (up to 1140 Vpeak) but lacks 150 Mbps capability for high-speed feedback loops. | Prefer for ultra-high-voltage systems where speed is secondary to isolation robustness. |
Compared with ADUM141DARZ and ISO6763DR, SI8463BB-B-IS1R uniquely delivers six-channel 150 Mbps operation in narrow-body SOIC while meeting 2500 VRMS reinforced insulation - optimizing board space, timing performance, and system-level reliability in compact power converters.

SI8463BB-B-IS1R is certified to UL 1577 (2500 VRMS), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (VDE 0884-2), with production-tested isolation up to 3000 VRMS for 1 second. These approvals cover reinforced insulation for industrial and automotive use cases.
Can SI8463BB-B-IS1R operate with mismatched supply voltages on VDD1 and VDD2?
Yes, SI8463BB-B-IS1R supports independent VDD1 and VDD2 supplies ranging from 2.70 V to 5.5 V each. This enables level-shifting between 3.3 V controllers and 5 V analog subsystems, with verified timing and drive strength across all combinations per Tables 3–5.
What is the channel-to-channel skew specification for SI8463BB-B-IS1R?
The channel-to-channel skew for SI8463BB-B-IS1R is specified as ≤1.8 ns maximum (tPSK) at 150 Mbps, 5 V, and –40 °C to +125 °C. This value is measured between any two output channels on the same side (VDD2 domain) and ensures synchronized PWM edge delivery in multi-phase systems.
