Product details
Overview
SI8460AA-B-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, <1.5 ns pulse width distortion, and 0.5 ns channel-to-channel skew. It operates across 2.70–5.5 V supply rails and delivers <6 mA per channel at 100 Mbps (5 V), enabling high-speed signal isolation in motor control and isolated power supplies.
For engineers reviewing the SI8460AA-B-IS1 datasheet, SI8460AA-B-IS1 pinout, SI8460AA-B-IS1 application, or SI8460AA-B-IS1 equivalent, key selection criteria include its 2500 VRMS reinforced insulation rating, 25 kV/µs common-mode transient immunity, –40 to 125 °C operation at full speed, and compatibility with 15 pF capacitive loads across industrial and automotive subsystems.
Technical Context
The SI8460AA-B-IS1 implements capacitive isolation with on-chip RF modulation/demodulation circuitry, eliminating magnetic coupling and startup initialization delays. Its dual-die architecture separates input and output domains, supporting independent VDD1/VDD2 supplies for level-shifting between 2.70 V and 5.5 V logic domains without external components beyond bypass capacitors.
Timing performance is guaranteed across temperature and voltage: propagation delay skew remains ≤3.0 ns (P-P), channel skew ≤1.8 ns, and minimum pulse width is 6.0 ns at 150 Mbps. The device achieves 60-year lifetime at rated working voltage and meets IEC 60747-5-2, UL 1577, and CSA Component Notice 5A safety standards for reinforced insulation.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD1 | Primary-side power supply | Supplies input-side logic and isolation transmitter; accepts 2.70–5.5 V; requires local 0.1 µF bypass capacitor. |
| GND1 | Primary-side ground reference | Return path for VDD1 domain; must be separated from GND2 by ≥3.9 mm PCB clearance for safety compliance. |
| IN1–IN3 | Input signal channels (side 1) | Accept CMOS/TTL-compatible signals; VIH ≥2.0 V, VIL ≤0.8 V; no external pull-ups required. |
| OUT1–OUT3 | Output signal channels (side 2) | Drive 15 pF loads at 150 Mbps; VOH ≥VDD2–0.4 V, VOL ≤0.4 V; output impedance ≈85 Ω for controlled-impedance routing. |
| VDD2 | Secondary-side power supply | Supplies output-side logic and receiver; independent of VDD1; enables galvanic separation of power domains. |
| GND2 | Secondary-side ground reference | Return path for VDD2 domain; forms isolation barrier with GND1; defines common-mode rejection boundary. |
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 |
|---|---|---|---|
| ADUM140D0BRIZ | Four-channel, 150 Mbps, 2.5 kVRMS, SOIC-16; higher typical supply current (7.5 mA/ch @ 100 Mbps, 5 V). | Lacks sixth channel; requires two devices for full six-signal isolation, increasing layout area and BOM count. | Choose when only four isolated signals are needed and ADI ecosystem integration is prioritized. |
| ISO6760QDWR | Six-channel, 50 Mbps, 5 kVRMS, SOIC-16; lower data rate but higher isolation rating and AEC-Q100 Grade 1 qualification. | Not suitable for 100+ Mbps timing-critical links; better suited for high-reliability automotive body electronics than motor control. | Choose when 5 kVRMS isolation and automotive qualification outweigh speed requirements. |
Compared with ADUM140D0BRIZ and ISO6760QDWR, SI8460AA-B-IS1 uniquely balances six-channel count, 150 Mbps speed, 2.5 kVRMS safety rating, and ultra-low power-making it optimal for space-constrained industrial inverters requiring precise multi-signal synchronization without thermal derating.

FAQ
What is the maximum data rate supported by the SI8460AA-B-IS1?
The SI8460AA-B-IS1 supports a maximum data rate of 150 Mbps across all six channels under specified conditions (VDD = 5 V, TA = –40 to 125 °C, CL = 15 pF). This is confirmed in Table 3 timing characteristics for Si846xBx variants, and the SI8460AA-B-IS1 part number corresponds to the "B" speed grade per Skyworks' ordering guide.
Does the SI8460AA-B-IS1 require external components for basic operation?
No, the SI8460AA-B-IS1 requires only 0.1 µF bypass capacitors on VDD1 and VDD2 pins. Unlike optocouplers or transformer-based isolators, it needs no external resistors, level shifters, or initialization circuitry - the device outputs valid data within 40 µs of power application and operates across 2.70–5.5 V without configuration.
What safety certifications apply to the SI8460AA-B-IS1?
The SI8460AA-B-IS1 is certified to UL 1577 (2500 VRMS, 1 min), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (reinforced insulation). These certifications are explicitly stated in Table 6 and apply to the NB SOIC-16 package variant, including SI8460AA-B-IS1.
Can the SI8460AA-B-IS1 operate with different supply voltages on each side?
Yes, SI8460AA-B-IS1 supports independent VDD1 and VDD2 supplies ranging from 2.70 V to 5.5 V each. This enables level translation between 3.3 V microcontrollers and 5 V gate drivers or analog circuits, as verified in Tables 1, 3, 4, and 5 of the datasheet under recommended operating conditions and electrical characteristics.
Is the SI8460AA-B-IS1 pin-compatible with other members of the Si846x family?
Yes, all Si8460/61/62/63 variants share identical 16-pin narrow-body SOIC pinouts and package dimensions. The SI8460AA-B-IS1 uses the same pin mapping as SI8461AA-B-IS1 and SI8462AA-B-IS1 - confirmed in Section 4 "Pin Descriptions" and Package Outline (page 30) of the datasheet - allowing drop-in replacement within the same speed and channel count group.
