DESCRIPTION
Description
OVERVIEW
Product Overview
ISO1540DR is a bidirectional I2C digital isolator from Texas Instruments, classified as an isolated interface device. It transfers I2C bus signals between circuits with different ground potentials or reference levels while blocking DC and low-frequency current paths. The device integrates isolation channels and I2C buffer circuitry to support isolated transmission of bidirectional data and clock lines. Typical uses include isolating I2C masters from slaves or separating voltage domains in power supplies, data acquisition, and industrial control systems. It is often used where electrical isolation is needed to avoid ground loops or protect low-voltage circuitry. Specific isolation ratings, data rates, and supply ranges should be confirmed from the original datasheet.
APPLICATIONS
Applications
- Isolate I2C communication between master and slave devices in industrial control systems.
- Separate I2C buses with different ground references in data acquisition systems.
- Transfer I2C configuration or monitoring signals in isolated power modules.
- Protect low-voltage I2C devices from high-voltage effects in multi-voltage-domain systems.
FEATURES AND BENEFITS
Features and Benefits
- Provides bidirectional I2C signal isolation for data and clock lines.
- Blocks ground loops and common-mode interference to help improve communication integrity.
- Suitable for interfaces between different ground references or voltage domains.
- Integrates I2C buffering to work with common I2C buses.
ADDITIONAL DETAILS
Additional Details
When purchasing, verify package type, operating temperature range, isolation rating, and channel direction against the target application, and refer to the original datasheet. Different batches or suffixes may correspond to different parameters, so confirm the specific ordering part number.
Verify product details against the manufacturer datasheet before purchase.
