Overview

Description

SI8605AD-B-IS is Silicon Labs’ isolated digital interface IC (iCoupler family). It provides galvanic isolation between two digital domains, enabling safe data transfer across ground differences. The AD-B-IS variant is an industrial-grade package designed to support I2C/SMBus-style signaling and other bidirectional digital lines, commonly used to isolate a host MCU from high-voltage or noisy peripherals. Key features include high isolation voltage, bidirectional channels, low propagation delay, and good common-mode transient immunity. It requires supplies on both sides and proper bypassing. Typical applications: industrial automation, motor drives, power electronics, and medical equipment. Pinout is an 8-pin package with A-side and B-side connections separated by the isolation barrier. For exact electrical ratings, bus speeds, and packaging, consult the datasheet.

Features

Key features of SI8605AD-B-IS (typical):
- Five isolated, unidirectional digital channels (iCoupler technology)
- Dual-supply isolated architecture (VDD1 on one side, VDD2 on the other)
- Isolation rating around 2.5 kV RMS (per standard digital isolators)
- Data rate up to ~25 Mbps per channel
- Propagation delay in the tens of nanoseconds range
- Wide operating supply: compatible with 3.3V and 5V logic families
- Temperature range: industrial (-40°C to +125°C)
- Low power consumption and compact package
- Robust ESD protection on I/O pins
- Suitable for interfaces like SPI, I2C, UART, and general purpose digital signals
- Package options typical for ISO devices (surface-mount, compact form)
Notes: Always verify exact figures (isolation rating, delay, and package) in the latest datasheet for your specific lot/revision.

Package

8-pin SOIC (SOP-8) package.

Pinout

8 pins. It is a single-channel, bidirectional digital isolator (galvanic isolation) used to isolate a signal line between two ground domains (commonly for I2C/SMBus-type signals).
