Analog Switches - Special Purpose datasheet and documents for MAX4889AETO+T

MAX4889AETO+T

Analog Switches - Special Purpose Overview

The MAX4889AETO+T is an octal single-pole/double-throw (8 x SPDT) high-speed passive switch designed for routing PCI Express data between four destinations. It operates from a single +3.0V to +3.6V power supply and supports PCIe Gen I and Gen II data rates up to 5.0Gbps. The device features a low same-pair skew of 7ps, a maximum on-resistance of 7 Ohms, and a maximum quiescent current of 120µA. It utilizes a flow-through pin configuration within a 42-pin TQFN package and functions over a temperature range of -40°C to +85°C.

Analog Switches - Special Purpose Feature Summary

Octal SPDT architecture supporting four half-lane PCIe paths
Low same-pair skew of 7ps for signal integrity
Single digital control input (SEL) for path selection
Flow-through pin configuration simplifies PCB layout

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 tape-and-reel packaging and lead-free compliance. Ensure the component matches the exact manufacturer part number to avoid functional discrepancies in high-speed switching applications.

Analog Switches - Special Purpose Selection Notes

Select this model when routing four half-lanes of PCIe data is required. Verify that the system design accommodates the 42-pin TQFN footprint and provides adequate bypass capacitance near the V+ pins to maintain signal integrity at 5.0Gbps.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX4888A/MAX4889A family of high-speed passive switches. While the MAX4888A handles two half-lanes in a 28-pin package, the MAX4889A scales this capability to four half-lanes using a 42-pin TQFN package, maintaining identical electrical characteristics and control logic.
