SI8662EC-AS1

Digital Isolators Overview

The SI8662EC-AS1 is a six-channel unidirectional digital isolator from the Si866x series, manufactured by Skyworks Solutions. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 3750 Vrms. The device supports data rates up to 150 Mb/s and features a propagation delay of 8 ns. It operates within a supply voltage range of 2.5 V to 5.5 V and consumes 8.8 mA of operating current. The component is housed in a 16-pin SOIC package and is qualified for automotive applications, functioning reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides high-speed signal transmission with low propagation delay via capacitive coupling

Digital Isolators Procurement Notes

Verify the exact part number against official Skyworks documentation to ensure correct insulation rating and channel configuration. Confirm that the AS1 suffix corresponds to the standard tube packaging variant rather than reel options. Cross-reference the datasheet specifications for thermal performance and pinout compatibility before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when a six-channel isolator with 3750 Vrms insulation is required for automotive or industrial use. Ensure the system design accommodates the 150 Mb/s data rate and 8 ns propagation delay characteristics. Verify that the SOIC-16 package dimensions fit the available PCB space and that the power supply voltage aligns with the 2.5 V to 5.5 V operational range.

Digital Isolators Part Context

This device belongs to the Si866x family of digital isolators, which are designed to replace traditional magnetic couplers. The family offers various channel counts and insulation ratings. The SI8662EC-AS1 specifically targets applications requiring six channels with high-speed performance and automotive-grade durability, distinguishing it from lower-rated or non-automotive variants in the same series.

Digital Isolators Replacement Considerations

Check Skyworks documentation for direct replacements such as the SI8662BD-B-IS1 for higher insulation ratings or other Si866x variants with different channel configurations. Ensure any substitute maintains the same SOIC-16 footprint and unidirectional polarity if pin compatibility is critical.
