MAX7367EUP+

Analog Switches - Special Purpose Overview

The MAX7367EUP+ is a bidirectional, four-channel I2C switch manufactured by Analog Devices Inc./Maxim Integrated. It expands the main I2C bus up to four extended buses and operates within a supply voltage range of 2.3V to 5.5V. The device supports I2C-compatible Normal or Fast Mode with a maximum clock frequency of 400 kHz. It features a typical on-resistance of 16Ω and low standby current of 0.1µA. The component is housed in a 20-pin TSSOP package and functions over an operating temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Four-channel bidirectional expansion isolates bus loading and allows multiple devices with identical addresses to communicate simultaneously.
• Supports voltage-level translation between the main bus and extended buses while maintaining transparency for signals.
• Includes interrupt inputs allowing devices on extended buses to signal the master on the main bus.

Analog Switches - Special Purpose Applications

• Servers
• RAID systems
• Cellular Phones
• Base Stations
• PCs

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm lead-free status and compliance requirements. Confirm that the 20-pin TSSOP package matches the design footprint. Ensure the selected variant aligns with the required channel configuration and address pin availability for the target application.

Analog Switches - Special Purpose Selection Notes

Select this component when expanding I2C bus capacity beyond standard limits or when connecting multiple peripherals sharing the same slave address. Consider the MAX7369 if multiplexing functionality is preferred over simultaneous switching. Verify that the system power supply falls within the 2.3V to 5.5V operational range.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX7367/MAX7368/MAX7369 family of 4-channel I2C switches/multiplexers. While the MAX7368 utilizes a 16-pin package, the MAX7367EUP+ specifically uses a 20-pin TSSOP package. All variants share similar electrical characteristics but differ in address bit configurations and interrupt capabilities.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes include the MAX7368EUE+ (16-pin) and MAX7369EUP+ (20-pin). Verify pin compatibility and functional differences such as multiplexer versus switch operation before replacement.

Analog Switches - Special Purpose FAQ

Can the MAX7367EUP+ be used as a voltage translator?

Yes, it can translate voltages from the main bus to the extended buses, provided the output voltage does not exceed the lowest bus voltage.

How are device addresses configured?

Addresses are set via external hardware pins A0 and A1, allowing for up to four unique device addresses.

Does the device support hot insertion?

Yes, the MAX7367EUP+ supports hot insertion capabilities.
