MAX7356EUG+T

Analog Switches - Special Purpose Overview

The MAX7356EUG+T is a 1-to-8 I2C bus switch and multiplexer manufactured by Analog Devices Inc. (Maxim Integrated). It expands a single main I2C bus to eight extended buses, enabling communication with devices that have conflicting slave addresses. The device operates on a supply voltage ranging from 2.3V to 5.5V and supports both Standard-Mode (100kbps) and Fast-Mode (400kbps) I2C interfaces. It features low on-resistance switches, logic-level translation, and 5.5V-tolerant inputs. The component is housed in a 24-pin TSSOP package and is specified for operation over an extended temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Expands a single main I2C bus to any combination of eight extended I2C buses to resolve slave address conflicts.
• Supports hot insertion and provides logic-level translation between different voltage domains.
• Features three address control inputs allowing multiple devices with identical IDs to coexist on the same bus.
• Includes a bidirectional RST/INT pin that functions as an active-low reset input and interrupt output.

Analog Switches - Special Purpose Applications

• Servers
• RAID systems
• Base stations
• Control and automation devices
• SFP control interfaces

Analog Switches - Special Purpose Procurement Notes

Verify the ordering suffix 'EUG+' corresponds to the 24-pin TSSOP package and lead-free/RoHS compliance. Confirm the specific revision level matches the design requirements. Ensure the supplier source is authorized to guarantee authenticity. Check for any regional distribution restrictions or availability constraints before finalizing procurement plans.

Analog Switches - Special Purpose Selection Notes

Select this component when expanding I2C connectivity to resolve address conflicts among multiple peripherals. Choose the MAX7356 variant if enhanced lock-up detection features are not required. Verify that the system voltage falls within the 2.3V to 5.5V operating range. Ensure the package type aligns with the PCB layout constraints and thermal management strategy.

Analog Switches - Special Purpose Part Context

The MAX7356 belongs to a family of 1-to-8 I2C switches/multiplexers alongside the MAX7357 and MAX7358. While all share similar core switching capabilities, the MAX7356 operates in basic mode only, lacking the built-in timer and bus lock-up detection found in the other variants. This makes it suitable for applications where simpler bus expansion is sufficient without advanced fault monitoring.

Analog Switches - Special Purpose Replacement Considerations

The MAX7357EUG+ and MAX7358EUG+ are functionally compatible alternatives within the same package. They offer additional enhanced mode features such as bus lock-up detection and isolation. If these diagnostic features are unnecessary, the MAX7356 remains the appropriate choice. Other families may require significant schematic changes due to interface differences.
