Analog Switches - Special Purpose datasheet and documents for MAX4889ETO+T

MAX4889ETO+T

Analog Switches - Special Purpose Overview

The MAX4889ETO+T 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 operates from a single power supply ranging from 1.65V to 3.6V and supports PCIe Gen I data rates up to 2.5Gbps. The device features a maximum on-resistance of 7Ω, a maximum turn-on time of 250ns, and a maximum turn-off time of 50ns. It is housed in a 42-pin TQFN package with dimensions of 3.5mm x 9.0mm and includes an exposed paddle connected to ground.

Analog Switches - Special Purpose Feature Summary

Single digital control input (SEL) switches signal paths between common and normally open/closed terminals
Low same-pair skew of 7ps ensures minimal timing differences within differential pairs
Flow-through pin configuration simplifies PCB layout and design procedures

Analog Switches - Special Purpose Applications

Desktop Computers
Servers/Storage Area Networks
Laptops

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix 'T' against official manufacturer documentation to confirm tape-and-reel packaging requirements. Ensure the component matches the exact part number MAX4889ETO+T before procurement. Cross-reference the datasheet revision date to confirm compatibility with current design specifications.

Analog Switches - Special Purpose Selection Notes

Select this component when eight independent PCIe lanes require switching between two destinations using a single control signal. Verify that the application environment remains within the specified -40°C to +85°C operating temperature range. Confirm that the board layout accommodates the 42-pin TQFN footprint and provides adequate thermal dissipation for the exposed paddle.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX4888/MAX4889 family of high-speed passive switches manufactured by Analog Devices / Maxim Integrated. While the MAX4888 offers four channels in a smaller package, the MAX4889 provides eight channels in a larger form factor. Both devices share identical electrical characteristics and control logic for PCIe lane reallocation.
