MAX4899EETE+T

Analog Switches - Special Purpose Overview

The MAX4899EETE+T is a dual 3:1 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 pins and fault tolerance up to +5.5V shorts. It includes an enable input (EN) and charge-pump enable (QP) for power management, housed in a 16-pin TQFN package.

Analog Switches - Special Purpose Feature Summary

• Supports USB 2.0 high-speed data switching alongside low- and full-speed signaling requirements.
• Provides robust overvoltage fault protection and ±15kV ESD protection on common terminals.
• Features active-low enable and charge-pump control inputs for optimized power consumption.

Analog Switches - Special Purpose Applications

• Switching USB connectors between host ports and peripheral devices
• Routing audio or video signals through USB interfaces
• Portable GPS navigation systems

Analog Switches - Special Purpose Procurement Notes

Verify the component designation against official manufacturer documentation to confirm the specific suffix indicates tape-and-reel packaging. Ensure that the ordering information matches the required configuration before finalizing procurement plans.

Analog Switches - Special Purpose Selection Notes

Select this model when a dual 3:1 multiplexer configuration is required for USB 2.0 compliance. Consider the MAX4899AE variant if four-channel switching per side is necessary instead of three.

Analog Switches - Special Purpose Part Context

This component belongs to the MAX4899 series of USB 2.0 high-speed multiplexers manufactured by Analog Devices / Maxim Integrated. It serves as a specialized interface switch for managing multiple data sources within portable electronic devices.

Analog Switches - Special Purpose Replacement Considerations

The MAX4899AEETE+T is a functional alternative offering a dual 4:1 configuration instead of the 3:1 layout found in this part number.

Analog Switches - Special Purpose FAQ

How does the QP pin affect operation?

Driving the QP pin high disables the internal charge pump, which reduces quiescent current but increases on-resistance and limits the analog signal range to 0V to 1.5V.

What is the function of the EN pin?

The EN pin acts as an active-low enable; driving it high places all channels into a high-impedance state and shuts off the charge pump for minimum power consumption.
