MAX7356EUG+

Analog Switches - Special Purpose Overview

The MAX7356EUG+ is an 8-channel I2C switch/multiplexer in a 24-pin TSSOP package. It expands the main I2C bus to eight extended buses, allowing isolation of devices with address conflicts. Operating from a 2.3V to 5.5V supply, it supports standard-mode (100kbps) and fast-mode (400kbps) interfaces. The device features low on-resistance switches, logic-level translation, and 5.5V-tolerant inputs. It operates 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 extended buses for addressing multiple slave devices.
• Provides hardware isolation between the host bus and downstream buses to prevent address conflicts.
• Supports hot insertion and includes logic-level translation for mixed-voltage system integration.
• Features low standby current consumption and 5.5V-tolerant input pins.

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 specific suffix EUG+ corresponds to the 24-pin TSSOP package and lead-free/RoHS compliance status. Confirm the manufacturer designation as Analog Devices Inc./Maxim Integrated. Ensure the component meets the specified -40°C to +85°C operating temperature range requirements for your application environment.

Analog Switches - Special Purpose Selection Notes

Select this component when expanding I2C connectivity to multiple isolated segments is required. The MAX7356 provides basic switching functionality without enhanced lock-up detection features found in the MAX7357/MAX7358 variants. Consider the 24-pin TSSOP package constraints and verify that the 2.3V to 5.5V supply voltage aligns with your system power rails.

Analog Switches - Special Purpose Part Context

The MAX7356EUG+ belongs to the MAX7356/MAX7357/MAX7358 family of 1-to-8 I2C bus switches. While the MAX7356 offers fundamental multiplexing capabilities, the MAX7357 and MAX7358 include enhanced modes with bus lock-up detection and notification features. All variants share similar electrical characteristics and pin configurations but differ in register access and diagnostic capabilities.

Analog Switches - Special Purpose Replacement Considerations

The MAX7356ETG+ serves as a direct replacement offering the same functionality in a 24-pin TQFN-EP package. For applications requiring bus lock-up detection and isolation features, the MAX7357EUG+ or MAX7358EUG+ are suitable alternatives within the same family.
