MAX4888AETI/V+T

Analog Switches - Special Purpose Overview

The MAX4888AETI/V+T is a high-speed passive switch designed to route PCI Express data between two destinations. It features four single-pole/double-throw (4 x SPDT) channels, supporting PCIe Gen I and Gen II data rates up to 5.0 Gbps. The device operates from a single +3.0V to +3.6V power supply with a maximum quiescent current of 120µA. It utilizes a single digital control input (SEL) for switching signal paths. Key electrical parameters include an on-resistance of 7Ω maximum, same-pair skew of 7ps typical, and propagation delay of 50ps typical. The component is housed in a 28-pin TQFN package measuring 3.5mm x 5.5mm and operates over a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

• Supports PCIe Gen I and Gen II data rates up to 5.0Gbps
• Features low same-pair skew of 7ps typical
• Utilizes flow-through pin configuration for ease of layout
• Includes industry-compatible pinout

Analog Switches - Special Purpose Applications

• Desktop Computers
• Servers/Storage Area Networks
• Laptops

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and thermal management needs. Confirm lead-free status if RoHS compliance is mandatory for the target application environment.

Analog Switches - Special Purpose Selection Notes

Select this component when routing PCIe signals between two destinations using a quad SPDT configuration. Verify that the system requires a single digital control input for path selection. Ensure the operating voltage falls within the specified +3.0V to +3.6V range and that the 28-pin TQFN package fits the board layout constraints.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4888A/MAX4889A family of high-speed passive switches manufactured by Analog Devices / Maxim Integrated. The MAX4888A specifically provides four SPDT channels, whereas the MAX4889A variant offers eight channels. Both share similar electrical characteristics and are designed for reallocating PCIe lanes in computing systems.

Analog Switches - Special Purpose Replacement Considerations

The MAX4889AETO+ serves as a functional substitute offering eight channels instead of four. Verify pinout compatibility and channel count requirements before substitution. Ensure the replacement meets the same PCIe data rate and voltage specifications.
