I2C Address Converter Module SKU: CQRADDR001

I2C Address Converter Module

Description

LTC4316 I2C Address Translation Module is a practical I2C bus expansion tool designed to resolve I2C device address conflicts. This module can translate the fixed hardware address of an I2C device into a different communication address, enabling multiple devices with identical addresses to operate simultaneously on the same I2C bus.

Features

• Efficient Address Conflict Solution: Based on the LTC4316IMS chip, it can translate the fixed hardware address of an I2C device into 127 distinct communication addresses, effectively resolving address conflicts on the I2C bus.
• Wide Voltage Operating Range: Supports power supply voltages from 2.25V to 5.5V, ensuring compatibility with various logic level systems.
• Hardware-Level Transparent Translation: Configures address offsets through a resistive voltage divider network and performs real-time address translation, remaining entirely transparent to both master and slave devices.
• Flexible Address Configuration: Enables independent configuration of the high 3-bit and low 4-bit address offsets via the XORH/XORL pins using resistor voltage division, with support for quick switching via DIP switches.
• Industrial-Grade Protection Design: Features separate interfaces for the master side (SCLIN/SDAIN) and slave side (SCLOUT/SDAOUT), providing clear signal flow isolation.
• Standard Interface Compatibility: Equipped with dual interfaces—HY2.0mm 4P connectors and 2.54mm pin headers—for easy connection to various development boards and sensor modules.
