Product details
Overview
SI8460AB-A-IS1 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 and channel-to-channel skew as low as 0.5 ns. It delivers reinforced isolation up to 2500 VRMS and operates across –40 °C to +125 °C at supply voltages from 2.70 V to 5.5 V, enabling use in high-noise industrial motor control and isolated power supply feedback loops.
For engineers reviewing the SI8460AB-A-IS1 datasheet, SI8460AB-A-IS1 pinout, SI8460AB-A-IS1 application, or SI8460AB-A-IS1 equivalent, this page provides verified timing specs, safety certifications (UL, CSA, VDE), supply current behavior at 1/100 Mbps, and real-world design meaning for CMTI (25 kV/µs), pulse width distortion (≤1.5 ns), and output impedance (85 Ω).
Technical Context
The SI8460AB-A-IS1 implements capacitive isolation with on-chip RF modulation/demodulation circuitry, eliminating start-up initialization and enabling immediate data transmission after power-on. Its dual-die architecture separates input and output domains with galvanic isolation barriers rated for 2500 VRMS withstand voltage and 60-year lifetime at rated working voltage.
All six channels are unidirectional and independently powered-VDD1 supplies side A (inputs), VDD2 supplies side B (outputs)-supporting asymmetric supply configurations (e.g., 3.3 V on one side, 5 V on the other) while maintaining full timing performance and CMTI immunity of 25 kV/µs across the full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | Up to 150 Mbps - supports high-speed serial interfaces like SPI clocked at ≥75 MHz or isolated UART at 10+ Mbps without signal degradation. |
| Propagation Delay | 3.0–9.5 ns (typ/max) - enables sub-10 ns timing-critical applications such as gate driver feedback in SiC/GaN inverters. |
| Channel-Channel Skew | 0.5–1.8 ns (typ/max) - ensures precise synchronization across multiple isolated control signals in multi-phase motor drives. |
| Supply Current @ 100 Mbps | <6 mA per channel at 5 V - reduces thermal load and simplifies power budgeting in compact isolated DC-DC controllers. |
| Common-Mode Transient Immunity | 25 kV/µs - maintains signal integrity during fast-switching events in 650 V+ power stages without glitches or latch-up. |
| Isolation Withstand Voltage | 2500 VRMS (1 min) - meets reinforced insulation requirements for IEC 61010-1 and UL 1577 in industrial and medical auxiliary circuits. |
| Operating Temperature | –40 °C to +125 °C - validated for continuous operation at 150 Mbps in under-hood automotive and industrial ambient environments. |
Pinout & Package
SI8460AB-A-IS1 is housed in a RoHS-compliant 16-pin narrow-body SOIC package (5.3 mm width, 10.3 mm length) with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Pin 1 is marked with a dot; pin numbering follows counterclockwise convention from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side supply (input side) | Power for channels A1–A6 input receivers; accepts 2.70–5.5 V; bypass capacitor required. |
| GND1 | Primary-side ground (input side) | Reference for all input signals and VDD1; must be separated from GND2 by isolation barrier. |
| INA1–INA6 | Input signal terminals (side A) | CMOS-compatible inputs accepting 0–VDD1 logic; no external pull-ups needed. |
| VDD2 | Secondary-side supply (output side) | Power for channels B1–B6 output drivers; independent of VDD1; enables level-shifting. |
| GND2 | Secondary-side ground (output side) | Reference for all output signals and VDD2; forms isolated domain with VDD2. |
| OUTB1–OUTB6 | Output signal terminals (side B) | CMOS outputs driving 4 mA sink/source; 85 Ω nominal output impedance for controlled-impedance trace matching. |
Key Features
| Feature | Design Value |
|---|---|
| No start-up initialization | Valid output data within 40 µs of power application - eliminates boot-time delays in safety-critical power-on sequencing. |
| Pulse width distortion | ≤1.5 ns (typ) - preserves duty cycle fidelity in PWM isolation for precision motor phase control. |
| Transient immunity | 25 kV/µs common-mode rejection - prevents false triggering during IGBT/SiC switch turn-off transients. |
| Low power at high speed | <6 mA per channel at 100 Mbps and 5 V - enables 6-channel isolation in thermally constrained space-constrained SMPS designs. |
| Wide supply range | 2.70–5.5 V on both sides - supports direct interface with 3.3 V microcontrollers and 5 V analog front-ends without level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital isolator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADUM260N0BRIZ-RL | 6-channel, 150 Mbps, 2.5 kVRMS, SOIC-16; lower max temp (105 °C); higher typical supply current at 100 Mbps (≈8.5 mA/ch @ 5 V). | Not rated for continuous 125 °C operation; less suitable for under-hood HEV inverter control. | Prefer SI8460AB-A-IS1 where extended temperature and lower power are critical. |
| ISO6760FDWR | 6-channel, 50 Mbps, 5 kVRMS, SOIC-16; wider creepage/clearance; higher isolation rating but lower speed. | Better suited for mains-connected equipment requiring 5 kVRMS basic insulation; insufficient for 100+ Mbps SPI or PWM. | Choose ISO6760FDWR only when higher isolation voltage outweighs speed requirement. |
Compared with ADUM260N0BRIZ-RL and ISO6760FDWR, SI8460AB-A-IS1 uniquely combines 150 Mbps speed, –40 °C to +125 °C operation, and ultra-low 6 mA/channel current at 100 Mbps-making it optimal for thermally demanding, high-bandwidth industrial and automotive isolation tasks where timing precision and power efficiency are co-prioritized.

FAQ
What is the maximum data rate supported by the SI8460AB-A-IS1?
The SI8460AB-A-IS1 supports a maximum data rate of 150 Mbps, verified across the full operating temperature range (–40 °C to +125 °C) and supply voltage range (2.70 V to 5.5 V). This specification applies to all six channels simultaneously and is measured with 15 pF load capacitance, making SI8460AB-A-IS1 suitable for high-speed SPI, isolated USB, and fast PWM applications.
Does the SI8460AB-A-IS1 require external components for startup or biasing?
No, the SI8460AB-A-IS1 requires no start-up initialization and begins transmitting valid data within 40 µs of power application. Only two 0.1 µF ceramic bypass capacitors-one each on VDD1 and VDD2-are required per the datasheet; no pull-up/down resistors, level shifters, or external clocks are needed for basic operation of SI8460AB-A-IS1.
What safety certifications does the SI8460AB-A-IS1 hold?
The SI8460AB-A-IS1 is certified to UL 1577 (2500 VRMS, 1 minute), CSA Component Acceptance Notice 5A (IEC 60950-1 and 61010-1), and VDE IEC 60747-5-2 (reinforced insulation). These certifications apply to the 2.5 kVRMS-rated narrow-body SOIC-16 variant and are production-tested to 3000 VRMS for 1 second, confirming SI8460AB-A-IS1's compliance in safety-critical industrial and medical auxiliary circuits.
Can SI8460AB-A-IS1 operate with different supply voltages on each side?
Yes, SI8460AB-A-IS1 supports independent supply rails: VDD1 (2.70–5.5 V) powers the input side (INA1–INA6), and VDD2 (2.70–5.5 V) powers the output side (OUTB1–OUTB6). This allows level-shifting-for example, interfacing a 3.3 V FPGA to a 5 V gate driver-without external translators, and SI8460AB-A-IS1 maintains full 150 Mbps performance and timing specs across all valid VDD1/VDD2 combinations.
What is the channel-to-channel skew specification for SI8460AB-A-IS1?
The SI8460AB-A-IS1 has a maximum channel-to-channel skew of 1.8 ns (typical 0.5 ns) at 150 Mbps, measured between any two output channels (OUTB1–OUTB6) under identical conditions. This low skew enables precise timing alignment across multiple isolated control paths-critical in three-phase motor drives and synchronized multi-channel data acquisition where SI8460AB-A-IS1 delivers deterministic latency behavior.
