Product details
Overview
SI8460AA-A-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 <9.5 ns, 0.5 ns channel-to-channel skew, and 25 kV/µs common-mode transient immunity. It operates across 2.70–5.5 V supply rails and delivers <6 mA per channel at 100 Mbps (5 V), enabling high-speed isolation in motor control and isolated power supplies.
For engineers reviewing the SI8460AA-A-IS1R datasheet, SI8460AA-A-IS1R pinout, SI8460AA-A-IS1R application, or SI8460AA-A-IS1R equivalent, key selection criteria include its 2500 VRMS reinforced insulation rating, 60-year lifetime at rated voltage, –40°C to +125°C operation at full speed, and compatibility with 3.3 V and 5 V logic systems without level-shifting.
Technical Context
The SI8460AA-A-IS1R implements capacitive isolation using differential RF signaling across an on-chip SiO₂ barrier, eliminating magnetic coupling and startup initialization. Its architecture supports independent primary and secondary supply domains (VDD1/VDD2), enabling bidirectional or unidirectional channel configurations per side.
It achieves precise timing via matched internal delay paths and integrated output drivers with ~85 Ω nominal impedance-designed for controlled-impedance PCB routing. Safety compliance includes UL 1577 (2500 VRMS), CSA Component Notice 5A (IEC 61010-1/60950-1), and VDE IEC 60747-5-2 (reinforced insulation).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 150 Mbps - supports high-speed serial interfaces like SPI, RS-485 transceiver control, and gate driver feedback loops. |
| Propagation Delay | 3.0–9.5 ns (typ/max) - enables sub-10 ns timing-critical isolation in real-time motor control and ADC sampling synchronization. |
| Channel-Channel Skew | 0.5 ns (typ) - ensures deterministic phase alignment across all six channels for multi-signal isolation (e.g., three-phase PWM + fault signals). |
| Isolation Voltage | 2500 VRMS (1 min) - meets reinforced insulation requirements for industrial drives and EV battery management systems. |
| Supply Range | 2.70–5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V analog front-ends without external regulators. |
| CMTI | 25 kV/µs - suppresses noise-induced glitches in high-dV/dt environments such as IGBT/SiC inverter switching nodes. |
| Operating Temp | –40°C to +125°C at 150 Mbps - qualified for under-hood automotive and industrial ambient conditions without derating. |
Pinout & Package
SI8460AA-A-IS1R is housed in a RoHS-compliant 16-pin narrow-body SOIC package (5.3 mm width, 10.3 mm length), with creepage and clearance ≥3.9 mm per IEC 60664-1 and VDE-certified ≥4.7 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies input-side logic and isolation transmitter; accepts 2.70–5.5 V with bypass capacitor required. |
| GND1 | Primary-side ground reference | Return path for VDD1 domain; must be separated from GND2 by isolation barrier. |
| IN1–IN3 | Input signal terminals (primary side) | Accept CMOS/TTL logic inputs; VIH ≥2.0 V, VIL ≤0.8 V at 3.3/5 V operation. |
| VDD2 | Secondary-side power supply | Supplies output-side logic and isolation receiver; independent of VDD1 for level-shifting capability. |
| GND2 | Secondary-side ground reference | Return path for VDD2 domain; galvanically isolated from GND1. |
| OUT1–OUT3 | Output signal terminals (secondary side) | Drive CMOS loads with VOH ≥VDD2–0.4 V, VOL ≤0.4 V; 85 Ω output impedance requires PCB trace termination. |
| NC | No-connect pins | Pins 8 and 16 are internally unused; must remain unconnected per datasheet layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power at high speed | Consumes <6 mA per channel at 100 Mbps (5 V), reducing thermal load in dense PCB layouts and enabling fanless industrial enclosures. |
| No start-up initialization | Delivers valid output within 40 µs of power application-critical for safety-critical systems requiring immediate fault signal transmission. |
| Precise timing performance | 1.5 ns pulse width distortion and 2 ns propagation delay skew ensure accurate edge placement in time-sensitive feedback paths. |
| 60-year life at rated voltage | Validated lifetime under 2500 VRMS working voltage supports long-lifecycle deployments in infrastructure and energy systems. |
| High EMI immunity | 25 kV/µs CMTI rating prevents data corruption in noisy motor drive and power converter environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM140D0BRIZ | Four-channel, 150 Mbps, 2.5 kVRMS, 16-lead SOIC; higher per-channel supply current (7.7 mA @ 100 Mbps, 5 V). | Limited to four channels; unsuitable for six-signal isolation without stacking or additional devices. | Select when channel count can be reduced and ADI ecosystem integration is prioritized. |
| ISO6760QDWR | Six-channel, 50 Mbps, 5 kVRMS, 16-lead SOIC; lower data rate but higher isolation rating and AEC-Q100 Grade 1 qualification. | Better suited for automotive body electronics where 150 Mbps is unnecessary but 5 kVRMS and temperature grade are mandatory. | Select for automotive chassis applications requiring extended temperature range and higher isolation voltage. |
Compared with ADUM140D0BRIZ and ISO6760QDWR, the SI8460AA-A-IS1R uniquely balances six-channel count, 150 Mbps speed, and 2500 VRMS rating in a standard SOIC footprint-making it optimal for space-constrained industrial inverters needing both bandwidth and reliability.

FAQ
What is the maximum data rate supported by the SI8460AA-A-IS1R?
The SI8460AA-A-IS1R supports a maximum data rate of 150 Mbps under typical operating conditions (VDD = 5 V, TA = 25°C, CL = 15 pF). This is confirmed in Table 3 of the Skyworks datasheet Rev. 1.6 for the Si846xBx variant, which includes SI8460AA-A-IS1R. The device maintains this rate across its full –40°C to +125°C operating temperature range.
Does the SI8460AA-A-IS1R require external components for basic operation?
Yes-the SI8460AA-A-IS1R requires only VDD bypass capacitors (0.1 µF ceramic) on both VDD1 and VDD2 pins for stable operation. No external resistors, transformers, or initialization firmware are needed, as stated in the product description and Section 3.1 of the datasheet. This simplifies BOM and reduces board area versus optocoupler-based solutions.
What safety certifications apply to the SI8460AA-A-IS1R?
The SI8460AA-A-IS1R is certified to UL 1577 (2500 VRMS, 1 minute), CSA Component Notice 5A (IEC 61010-1/60950-1), and VDE IEC 60747-5-2. These approvals cover reinforced insulation for industrial and automotive applications, with working voltage ratings up to 300 VRMS (reinforced) per CSA and 560 Vpeak (basic) per VDE, as detailed in Table 6 of the datasheet.
Can the SI8460AA-A-IS1R operate with different supply voltages on each side?
Yes-the SI8460AA-A-IS1R supports independent supply domains: VDD1 (2.70–5.5 V) powers the input side, and VDD2 (2.70–5.5 V) powers the output side. This enables level translation between 3.3 V controllers and 5 V peripherals without external level shifters, as verified in Tables 1 and 3–5 of the datasheet across 2.7 V, 3.3 V, and 5 V operating points.
Is the SI8460AA-A-IS1R recommended for new designs?
No-Skyworks explicitly marks the Si8460/61/62/63 family as "Not Recommended for New Designs" in Rev. 1.6 of the datasheet (August 11, 2021). While fully functional and supported, designers are advised to evaluate newer Skyworks isolators (e.g., Si86xx or Si88xx families) for enhanced features, longevity, and roadmap alignment.
