MAX7369EUP+T

Analog Switches - Special Purpose Overview

The MAX7369EUP+T is a bidirectional, four-channel I2C multiplexer that expands the main I2C bus to four extended buses. It connects the main bus to one channel at a time via internal control register writes. The device operates on a single supply voltage ranging from 2.3V to 5.5V and supports I2C Normal Mode (100kHz) and Fast Mode (400kHz). It features low standby current of 0.1µA typical and low on-resistance of 16Ω typical. The component includes interrupt inputs for each channel and an open-drain interrupt output. It is housed in a 20-pin TSSOP package and functions over an extended temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Four-channel bidirectional I2C multiplexing with hardware address selection
• Supports clock stretch, synchronization, and arbitration protocols
• Integrated interrupt logic with active-low inputs and open-drain output
• Voltage-level translation capability between main and extended buses

Analog Switches - Special Purpose Applications

• Servers and RAID systems
• Cellular phones and base stations
• PCs and multimedia electronics
• SAN/NAS storage arrays

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix matches the required package type and lead-free compliance status. Confirm the manufacturer designation aligns with Analog Devices or Maxim Integrated specifications. Ensure the component meets RoHS directives if applicable to the target assembly process. Cross-reference the part number against official distributor catalogs to confirm availability and authenticity before procurement.

Analog Switches - Special Purpose Selection Notes

Select this component when expanding an I2C bus to multiple isolated segments requiring exclusive channel access. It is suitable for systems needing voltage translation between different bus domains. Consider the MAX7367 or MAX7368 if simultaneous multi-channel connectivity or hardware reset functionality is required instead of software-controlled state restoration.

Analog Switches - Special Purpose Part Context

The MAX7369 belongs to the MAX7367/MAX7368/MAX7369 family of 4-channel I2C switches and multiplexers. While the MAX7367 and MAX7368 function as switches allowing multiple channels to be active simultaneously, the MAX7369 operates strictly as a 1:4 multiplexer. All variants share similar pinouts and electrical characteristics but differ in address bit configurations and control register structures.
