MAX4899AEETE+T

Analog Switches - Special Purpose Overview

The MAX4899AEETE+T is a dual 4:1 analog multiplexer designed for USB 2.0 high-speed applications at 480Mbps, supporting low- and full-speed signaling. It operates from a single 2.7V to 3.6V power supply with a typical on-resistance of 4Ω and a -3dB bandwidth of 425MHz. The device features ±15kV ESD protection on COM terminals and +5.5V fault tolerance. It includes an enable input (EN) for high-impedance shutdown and a charge-pump enable (QP). Packaged in a 16-pin TQFN (3mm x 3mm), it operates over the -40°C to +85°C temperature range.

Analog Switches - Special Purpose Feature Summary

• Dual 4:1 multiplexer architecture routing two differential pairs across four selectable channels
• Fault-tolerant design compliant with USB 2.0 specifications including overvoltage protection
• High electrostatic discharge protection rated at ±15kV on common terminals
• Ultra-low standby current capability via active-low enable and charge-pump disable inputs

Analog Switches - Special Purpose Applications

• Switching USB connectors between host ports and peripheral devices
• Routing signals between USB interfaces and serial communication lines
• Multiplexing audio or video data streams alongside USB connections
• Portable GPS units and digital still cameras requiring signal path selection

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'EETE+T' against official manufacturer documentation to confirm tape-and-reel packaging and lead-free status. Ensure the ordering code matches the dual 4:1 configuration required for the application. Cross-reference the component marking 'AEZ' to validate authenticity and revision level before integration into production systems.

Analog Switches - Special Purpose Selection Notes

Select this component when a dual 4:1 switching topology is required for USB 2.0 high-speed data lines. The MAX4899E variant serves as the alternative if only three channels per pair are needed. Consider the exposed paddle requirement for thermal management and ground connection during PCB layout to maintain signal integrity and device reliability.

Analog Switches - Special Purpose Part Context

This part belongs to the MAX4899 family of USB 2.0 high-speed multiplexers manufactured by Analog Devices / Maxim Integrated. It shares core electrical characteristics with the MAX4899E but differs in channel count. Both variants utilize the same 16-pin TQFN package and support identical voltage ranges and protection features for portable electronics.

Analog Switches - Special Purpose Replacement Considerations

The MAX4899EETE+T is functionally similar but offers a dual 3:1 configuration instead of 4:1. Verify pin compatibility and channel requirements before substitution.
