MAX7356ETG+

Analog Switches - Special Purpose Overview

The MAX7356ETG+ is a 1-to-8 I2C bus switch and multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It expands the main I2C bus to eight extended buses, enabling address conflict resolution. The device operates on a single supply voltage ranging from 2.3V to 5.5V and supports both Standard-Mode (100kbps) and Fast-Mode (400kbps) communication protocols. It is housed in a 24-pin TQFN package with an exposed pad 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 host I2C bus to eight independent downstream buses to resolve slave address conflicts
• Supports hot insertion and logic-level translation across the specified supply voltage range
• Features low standby current consumption for power-sensitive applications
• Includes three hardware-selectable address bits for multiple device integration

Analog Switches - Special Purpose Applications

• Servers and RAID systems requiring expanded I2C connectivity
• Base stations and networking equipment managing multiple peripheral devices
• Control and automation devices needing isolated bus segments
• SFP control interfaces for optical transceiver management

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix ETG+ corresponds to the 24-pin TQFN package configuration. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the selected variant matches the required operational mode, as enhanced diagnostic features are exclusive to the MAX7357/MAX7358 family members.

Analog Switches - Special Purpose Selection Notes

Select the MAX7356ETG+ when only basic switching functionality is required without lock-up detection or preconnection wiggle tests. Verify that the system supply voltage falls within the 2.3V to 5.5V range. Consider the MAX7357 or MAX7358 if bus isolation, fault notification, or automatic recovery sequences are necessary for system reliability.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX7356/MAX7357/MAX7358 family of 1-to-8 I2C switches. While all variants share the same core switching architecture and pinout, the MAX7356 represents the basic mode version. It lacks the enhanced diagnostic registers and timer-based lock-up detection found in the MAX7357 and MAX7358 models.

Analog Switches - Special Purpose Replacement Considerations

Direct functional replacements within the same package include the MAX7356EUG+ (TSSOP variant) or other MAX7356 family members. Cross-family substitutes require verification of I2C compatibility and voltage levels.
