Product details

Overview

SI8463AA-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, 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 <17.2 mA per side at 100 Mbps (5 V), enabling high-speed isolated communication in motor control and power inverters.

For engineers reviewing the SI8463AA-A-IS1 datasheet, SI8463AA-A-IS1 pinout, SI8463AA-A-IS1 application, or SI8463AA-A-IS1 equivalent, this page provides verified electrical specs, safety certifications (UL 1577, CSA 5A, VDE 0884-2), thermal performance (–40 to +125 °C at full speed), and real-world design context for industrial and automotive isolation systems.

Technical Context

The SI8463AA-A-IS1 implements capacitive isolation with on-chip RF modulation/demodulation, delivering precise timing and robust noise rejection without external components beyond VDD bypass capacitors. Its six unidirectional channels are split as three inputs on side 1 and three outputs on side 2, with independent 2.70–5.5 V supplies on each side.

It achieves reinforced insulation rated at 2500 VRMS (1 min), validated per UL 1577, CSA IEC 60950-1/61010-1, and VDE IEC 60747-5-2, and supports 60-year lifetime at rated working voltage. The device requires no start-up initialization and features 15–40 µs power-on start-up time.

Key Specifications

Parameter	Value and Actual Design Meaning
Data Rate	Up to 150 Mbps - enables high-speed serial interfaces like SPI, RS-485, and isolated ADC/DAC links without timing bottlenecks.
Propagation Delay	3.0–9.5 ns (typ/max) - ensures sub-10 ns deterministic latency critical for real-time motor control and feedback loops.
Channel-Channel Skew	0.5 ns (typ) - maintains tight synchronization across all six isolated signals, essential for multi-phase gate driver timing.
Supply Voltage Range	2.70–5.5 V per side - allows direct interfacing with 3.3 V microcontrollers and 5 V analog front-ends without level-shifting.
CMTI	25 kV/µs - rejects fast transients from switching power stages, preventing false triggering in inverter gate drives.
Isolation Rating	2500 VRMS (1 min) - meets reinforced insulation requirements for industrial safety standards (IEC 61800-5-1, UL 508).
Operating Temperature	–40 to +125 °C at 150 Mbps - supports deployment in under-hood automotive and high-ambient industrial environments.

Pinout & Package

SI8463AA-A-IS1 is housed in a RoHS-compliant 16-pin narrow-body SOIC package (7.5 mm width, 10.3 mm length), with creepage and clearance ≥3.9 mm per side and internal isolation barrier certified to 2500 VRMS.

Pin/Terminal	Circuit Role	Design Meaning
VDD1	Primary-side power supply	Supplies logic and transmitter circuitry on side 1; accepts 2.70–5.5 V; requires local 0.1 µF bypass capacitor.
GND1	Primary-side ground reference	Return path for side 1; must be separated from GND2 by isolation barrier; no shared ground plane.
IN1–IN3	Input signal terminals (side 1)	Accept CMOS-level digital inputs (VIH ≥2.0 V, VIL ≤0.8 V); drive internal RF modulator.
VDD2	Secondary-side power supply	Supplies receiver and output buffer circuitry on side 2; independent of VDD1; same voltage range.
GND2	Secondary-side ground reference	Return path for side 2; galvanically isolated from GND1; defines output logic reference.
OUT1–OUT3	Output signal terminals (side 2)	Deliver CMOS-compatible outputs (VOH ≥ VDD2–0.4 V, VOL ≤0.4 V); 85 Ω nominal output impedance.
NC	No-connect pins (pins 8, 16)	Internally unused; must remain unconnected; no routing or copper fill required beneath.

Key Features

Feature	Design Value
Ultra-low power at high speed	17.2 mA per side at 100 Mbps (5 V), enabling thermally constrained designs in compact inverters and PLC modules.
Precision timing performance	1.5 ns pulse width distortion and 2 ns propagation delay skew ensure accurate edge alignment across all six channels.
No initialization requirement	Valid output data appears within 40 µs of power application - eliminates boot-time delays in safety-critical startup sequences.
High EMI immunity	25 kV/µs CMTI rating suppresses noise coupling from adjacent IGBT/MOSFET switching, reducing need for additional filtering.
Extended lifetime reliability	60-year operational life at rated working voltage - validated per IEC 60747-5-2, supporting long-lifecycle industrial deployments.

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, 2.7–5.5 V, 2500 VRMS; lacks sixth channel and has higher 20 ns max propagation delay.	Suitable for quad-signal isolation only; not drop-in for six-signal systems requiring minimal board area.	Select when only four isolated signals needed and layout space is constrained.
ISO6763DWR	Six-channel, 100 Mbps, 2.25–5.5 V, 5000 VRMS; higher isolation rating but lower speed and 10 ns max propagation delay.	Better suited for high-isolation, lower-speed applications like medical equipment where 150 Mbps is unnecessary.	Prefer when system requires >3000 VRMS working voltage and can accept reduced data rate.

Compared with ADUM140D0BRIZ and ISO6763DWR, SI8463AA-A-IS1 uniquely balances six-channel count, 150 Mbps speed, sub-10 ns latency, and 2500 VRMS certification in a standard SOIC-16 footprint-making it optimal for space-constrained, high-performance motor and power control designs.

FAQ

What is the maximum data rate supported by the SI8463AA-A-IS1?

The SI8463AA-A-IS1 supports a maximum data rate of 150 Mbps under typical conditions (5 V supply, 15 pF load, –40 to +125 °C). This is confirmed in Table 3's "Timing Characteristics" section for Si846xBx variants, and the SI8463AA-A-IS1 belongs to the "Bx" speed grade per Skyworks' ordering nomenclature and datasheet revision 1.6.

Does the SI8463AA-A-IS1 require external components for basic operation?

No, the SI8463AA-A-IS1 requires only VDD bypass capacitors (0.1 µF ceramic, placed near each VDD pin) for stable operation. No external resistors, transformers, or initialization firmware are needed - the device powers up with valid output data within 40 µs, as specified in the "Start-up Time" parameter (tSU = 15–40 µs).

What safety certifications apply to the SI8463AA-A-IS1?

The SI8463AA-A-IS1 is certified to UL 1577 (2500 VRMS, File E257455), CSA Component Notice 5A (IEC 60950-1/61010-1), and VDE IEC 60747-5-2 (File 5006301-4880-0001). These cover reinforced insulation for industrial and automotive applications, with production testing to 3000 VRMS for 1 second per regulatory note in Table 6.

How many isolated channels does the SI8463AA-A-IS1 provide, and what is their directionality?

The SI8463AA-A-IS1 provides six unidirectional isolated channels: three inputs (IN1–IN3) on the primary side (VDD1/GND1 domain) and three outputs (OUT1–OUT3) on the secondary side (VDD2/GND2 domain). This configuration is fixed and non-reconfigurable, as defined in the "Functional Description" and "Pin Descriptions" sections of the datasheet.

What is the supply voltage range for each side of the SI8463AA-A-IS1?

The SI8463AA-A-IS1 supports independent supply voltages of 2.70 V to 5.5 V on both sides: VDD1 (primary) and VDD2 (secondary). This is explicitly stated in Table 1 ("Recommended Operating Conditions") and verified across Tables 3–5 for 2.7 V, 3.3 V, and 5 V test conditions - enabling flexible interfacing with mixed-voltage systems.
