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.
