SI86SO21BC-ISR

Digital Isolators Overview

The SI86SO21BC-ISR is a Skyworks Solutions digital isolator featuring two unidirectional channels with inverting outputs. It provides up to 6000 VRMS isolation voltage using capacitive coupling technology. The device supports high-speed data transmission rates from DC to 150 Mbps without requiring start-up initialization. It operates on a wide supply voltage range of 2.25 V to 5.5 V and is housed in an 8-SSOP package suitable for surface mount applications.

Digital Isolators Feature Summary

• Provides up to 6000 VRMS insulation voltage for enhanced safety barriers
• Features inverting output logic for signal inversion across the isolation barrier
• Supports high-speed operation from DC to 150 Mbps data rates
• Requires no start-up initialization sequence upon power application

Digital Isolators Applications

• Industrial automation systems requiring high-voltage isolation
• Medical equipment needing reinforced insulation barriers
• Power electronics interfaces for motor control circuits
• Smart grid infrastructure communication modules

Digital Isolators Procurement Notes

Verify that the specific suffix 'ISR' corresponds to the tape-and-reel packaging format rather than tube packaging when placing orders. Confirm the operating temperature range and moisture sensitivity level requirements align with your assembly process standards. Ensure the inverting output configuration matches your circuit design needs, as this variant differs from non-inverting counterparts within the same family.

Digital Isolators Selection Notes

Select this component when high isolation voltage ratings are critical for system safety compliance. The inverting output characteristic must be accounted for in logic design compared to standard non-inverting isolators. Consider the wide supply voltage capability for flexibility in different power domains. Verify that the 150 Mbps speed meets the bandwidth requirements of the target application interface.

Digital Isolators Part Context

This part belongs to the SI86SO2x series of digital isolators from Skyworks Solutions. It utilizes proprietary capacitive coupling technology to provide galvanic isolation between input and output sides. The series is designed for general-purpose applications requiring robust isolation performance in compact surface-mount packages.

Digital Isolators Replacement Considerations

Direct substitutes include other variants within the SI86SO2x family such as SI86SO21BC-IS for tube packaging or SI86SO21BE-IS4 for alternative pinout configurations. Non-inverting equivalents like SI8621BC-B-ISR offer similar electrical characteristics but lack the inverting output feature.
