MAX14509AEEVB+T

Analog Switches - Special Purpose Overview

The MAX14509AEEVB+T is a high-ESD-protected DPDT analog switch designed for multiplexing Hi-Speed (480Mbps) USB and analog signals. It operates from a +2.7V to +5.0V supply with a typical quiescent current of 12μA. The device features low on-resistance (2.4Ω typ) and low off-capacitance (3.3pF typ). It includes an internal negative charge pump allowing analog signal passage down to VCC - 5.0V. The part lacks VBUS detection and shunt resistors but provides an active-high enable input. It is housed in a 10-pin, 1.4mm x 1.8mm UTQFN package.

Analog Switches - Special Purpose Feature Summary

• Supports USB 2.0 Hi-Speed signaling and AC-coupled audio/video multiplexing
• Internal negative supply capability passes signals below ground without distortion
• Active-high enable input reduces supply current and sets channels to high impedance
• High ESD protection on COM pins up to ±15kV Human Body Model

Analog Switches - Special Purpose Applications

• Cell Phones
• MP3 Players
• Notebook Computers
• PDAs

Analog Switches - Special Purpose Procurement Notes

Verify the ordering suffix matches the specific functional configuration required. Confirm that the selected variant aligns with the necessary control inputs and fault protection features for the target application design.

Analog Switches - Special Purpose Selection Notes

Select this component when USB and audio switching is required without automatic VBUS detection or click-and-pop suppression. Ensure the system design accommodates the single-bit digital control logic and active-high enable requirements specified in the datasheet.

Analog Switches - Special Purpose Part Context

This device belongs to the MAX14508E–MAX14511E family of USB 2.0 Hi-Speed and Audio Switches. It shares the same core switching architecture and package as other variants in the series, differing primarily in the inclusion or exclusion of VBUS detection and shunt resistor features.

Analog Switches - Special Purpose Replacement Considerations

Direct substitutes within the same family include MAX14508E, MAX14509E, MAX14510E, and MAX14511E. Verify pin compatibility and functional differences regarding VBUS detection and enable lines before substitution.
