MAX7357EUG+T

Analog Switches - Special Purpose Overview

The MAX7357EUG+T is a 1-to-8 I2C bus switch and multiplexer housed in a 24-pin TSSOP package. It operates on a single supply voltage ranging from 2.3V to 5.5V with a maximum on-resistance of 24 ohms. The device supports standard-mode (100kbps) and fast-mode (400kbps) I2C interfaces, featuring a propagation delay of 0.3ns. Designed for extended temperatures between -40°C and +85°C, it includes enhanced mode capabilities such as bus lock-up detection, isolation, and notification via the bidirectional RST/INT pin.

Analog Switches - Special Purpose Feature Summary

• Enhanced mode operation with built-in timer for monitoring extended buses
• Bus lock-up detection and automatic isolation upon fault identification
• Bidirectional RST/INT pin providing hardware reset and interrupt notification
• Preconnection wiggle test to verify downstream bus state before connection

Analog Switches - Special Purpose Applications

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

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Confirm that the component matches the exact manufacturer part number required for your design. Ensure compliance with RoHS standards if applicable to your project requirements.

Analog Switches - Special Purpose Selection Notes

Select this component when expanding an I2C bus to multiple isolated segments requiring fault management. The MAX7357 is appropriate for designs needing lock-up detection and host notification features not available in basic switches. Consider the 24-pin TSSOP footprint and 2.3V to 5.5V supply compatibility during integration.

Analog Switches - Special Purpose Part Context

This device belongs to the MAX7356/MAX7357/MAX7358 family of 1-to-8 I2C switches. While all variants share the same physical package and basic switching functionality, the MAX7357 specifically adds enhanced diagnostic registers and lock-up detection capabilities compared to the MAX7356.

Analog Switches - Special Purpose Replacement Considerations

The MAX7356EUG+ serves as a functional substitute if bus lock-up detection and enhanced mode features are not required. Verify that the replacement part meets the same electrical specifications and package dimensions for direct board-level interchangeability.
