Product details
Overview
SI86S642EE-IS2R from Skyworks Solutions is a 4-channel, reinforced-isolation digital isolator with bidirectional signal capability, 150 Mbps data rate, 10 ns typical propagation delay, and 6000 VRMS isolation rating. It operates across 2.25–5.5 V supply rails on both sides and supports fail-safe default-high output mode in unpowered conditions - used in isolated motor control gate drivers and battery management system communication interfaces.
For engineers reviewing the SI86S642EE-IS2R datasheet, SI86S642EE-IS2R pinout, SI86S642EE-IS2R application, or SI86S642EE-IS2R equivalent, key selection criteria include its AEC-Q100 qualification, IEC 60747-17 reinforced insulation rating, Schmitt-trigger + CMOS input thresholds, tri-state output enable, and 36 ns input deglitch filter - all confirmed for this exact SOIC-16 WB package variant.
Technical Context
The SI86S642EE-IS2R implements RF-based on/off keying modulation across a semiconductor isolation barrier, eliminating startup initialization and enabling robust noise immunity without optical degradation. Its architecture supports independent undervoltage lockout (UVLO) and reset monitoring on both sides (VDD1/VDD2), with RSTB thresholds at ~1.7 V and UVLO hysteresis of 105–160 mV.
It features four isolated bidirectional channels with side-A and side-B enable inputs (EN1/EN2), selectable fail-safe output state (default high per -EE suffix), and integrated 36 ns input deglitch filters - all validated for automotive-grade operation from –40 °C to 125 °C and compliant with UL 1577, CSA 62368-1/60601-1, and VDE 60747-17.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data rate | DC to 150 Mbps - supports high-speed SPI, isolated ADC/DAC interfaces, and real-time motor control feedback loops. |
| Propagation delay | 10 ns typical - enables tight timing budgets in closed-loop power converter control and fast-response safety systems. |
| Isolation rating | 6000 VRMS for 1 minute - meets reinforced insulation requirements for industrial inverters and EV traction systems. |
| Supply voltage | 2.25–5.5 V per side - allows interoperability with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |
| Input filtering | 36 ns deglitch time - suppresses EFT bursts and switching noise in noisy motor drive environments. |
| Fail-safe mode | Default high output - ensures safe logic state during VDD1 loss in isolated gate driver enable paths. |
| Transient immunity | ≥100 kV/µs CMTI - maintains signal integrity under fast dv/dt transients in SiC/GaN power stages. |
Pinout & Package
SI86S642EE-IS2R uses a wide-body SOIC-16 (WB SOIC-16) package with creepage/clearance optimized for 6000 VRMS working voltage. Pin numbering follows standard SOIC-16 layout with isolation barrier between pins 1–8 (Side A) and 9–16 (Side B).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1, GND1 | Side A power supply | Provides bias for A-side transmitter circuits; requires 0.1 µF + 10 µF bypass capacitors. |
| A1–A4 | Side A digital I/O | Bidirectional isolated data channels; Schmitt-trigger + CMOS threshold inputs for noise immunity. |
| EN1 | Side A output enable | Active-high control for tristating all A-side outputs - used for bus arbitration or low-power sleep entry. |
| VDD2, GND2 | Side B power supply | Independent bias for B-side receiver circuits; supports different voltage domains than Side A. |
| B1–B4 | Side B digital I/O | Corresponding isolated outputs/inputs mirroring A1–A4; fail-safe default state set by -EE ordering option. |
| EN2 | Side B output enable | Active-high control for tristating all B-side outputs - enables independent side-level power gating. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM2402BRWZ | 4-channel, 25 Mbps max data rate; 50 ns propagation delay; 5000 VRMS isolation; no deglitch filter. | Suitable for lower-speed industrial I/O but not for 150 Mbps SPI or fast motor control loops. | Select when cost sensitivity outweighs speed/CMTI requirements and 5000 VRMS suffices. |
| ISO6742FDWR | 4-channel, 50 Mbps max data rate; 25 ns propagation delay; 5000 VRMS; no AEC-Q100 qualification. | Applicable in non-automotive industrial systems where extended temperature range is not required. | Choose for TI ecosystem designs needing I2C-compatible timing but not automotive-grade reliability. |

FAQ
What is the isolation rating and safety certification status of SI86S642EE-IS2R?
SI86S642EE-IS2R is rated for 6000 VRMS isolation per UL 1577 for 1 minute and carries reinforced insulation certification to IEC 60747-17. It is also certified to CSA 62368-1 and 60601-1, and CQC GB4943.1. All certifications are validated for the WB SOIC-16 package used in SI86S642EE-IS2R, supporting end-equipment approval in medical and industrial applications without additional barrier testing.
Does SI86S642EE-IS2R support fail-safe operation, and how is it configured?
Yes, SI86S642EE-IS2R implements selectable fail-safe mode via its ordering option suffix: the "-EE" indicates default-high output behavior when VDD1 is unpowered but VDD2 remains active. This is confirmed in Table 4 of the datasheet and ensures safe logic states in isolated gate driver enable paths during partial power loss - a critical requirement in motor control and BMS applications.
What is the purpose of the 36 ns input deglitch filter in SI86S642EE-IS2R?
The 36 ns input deglitch filter in SI86S642EE-IS2R removes sub-36 ns noise pulses from input signals, preventing false triggering in electrically noisy environments like motor drives and inverters. This feature is explicitly specified for the Si86S64x family in Section 3.4.5 and is implemented in hardware - ensuring reliable operation without software debouncing or external RC networks.
How does the RF modulation architecture of SI86S642EE-IS2R differ from traditional optocouplers?
SI86S642EE-IS2R uses RF on/off keying across a semiconductor isolation barrier instead of light-emitting diodes and phototransistors. This eliminates startup initialization delays, avoids LED aging and CTR degradation, provides superior CMTI (>100 kV/µs), and enables consistent 150 Mbps performance across temperature - all confirmed in Figure 7 and Section 2.1 of the datasheet for SI86S642EE-IS2R.
Is SI86S642EE-IS2R qualified for automotive applications, and what does AEC-Q100 Grade 1 mean?
Yes, SI86S642EE-IS2R is AEC-Q100 Grade 1 qualified, meaning it is tested and certified for operation from –40 °C to +125 °C ambient temperature and validated for automotive subsystems including onboard chargers, battery management systems, and traction inverters. This qualification covers stress tests for temperature cycling, humidity, and ESD - all performed on the exact SI86S642EE-IS2R device variant.
