Analog Switches - Special Purpose datasheet and documents for MAX4889AETO+

MAX4889AETO+

Analog Switches - Special Purpose Overview

The MAX4889AETO+ is an octal single-pole/double-throw (8 x SPDT) high-speed passive switch designed for routing PCI Express data between two possible destinations. It supports 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. Key electrical parameters include a maximum on-resistance of 7 Ohms, a turn-on time of 250 ns, and a turn-off time of 50 ns. It features low same-pair skew of 7ps and is housed in a 42-pin TQFN-EP package.

Analog Switches - Special Purpose Feature Summary

Octal SPDT configuration ideal for switching four half lanes of PCIe data
Single digital control input (SEL) simplifies signal path switching
Low same-pair skew ensures precise signal timing integrity
Flow-through pin configuration facilitates PCB layout

Analog Switches - Special Purpose Applications

Desktop Computers
Servers/Storage Area Networks
Laptops

Analog Switches - Special Purpose Procurement Notes

Verify the component authenticity by checking the manufacturer markings against the official datasheet specifications. Ensure the ordering suffix matches the required lead-free and RoHS-compliant packaging standards. Confirm that the specific package variant aligns with your board design requirements before finalizing procurement orders.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring the reallocation of PCIe lanes, such as splitting a 16-lane bus into multiple 8-lane buses for graphics applications. Consider the 42-pin TQFN package dimensions and the requirement for a single +3.0V to +3.6V supply voltage during the schematic capture phase.

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. While the MAX4888A provides a quad SPDT configuration, the MAX4889A offers an octal SPDT setup, making it suitable for more complex lane-switching scenarios in high-performance computing environments.
