MAX3450EEUD+T

Drivers, Receivers, Transceivers Overview

The MAX3450EEUD+T is a USB-compliant transceiver designed to interface low-voltage ASICs with USB devices. It fully complies with USB 1.1 and USB 2.0 standards, supporting full-speed (12Mbps) and low-speed (1.5Mbps) data rates. The device operates with a logic supply voltage (VL) ranging from +1.65V to +3.6V. It features integrated ±15kV ESD protection on the D+ and D- bidirectional bus connections. The component includes an internal linear regulator that provides a regulated VTRM output of 3.0V to 3.6V. Operating temperatures range from -40°C to +85°C. The package type is a 14-pin TSSOP.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix EEUD corresponds to the 14-pin TSSOP package configuration. Confirm RoHS compliance status as indicated by the plus sign in the part number. Ensure the supplier provides valid traceability documentation for Analog Devices / Maxim Integrated components. Check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when interfacing low-voltage ASICs with USB peripherals requiring USB 1.1/2.0 compliance. It is suitable for applications needing ±15kV ESD protection directly on the bus lines. Consider the MAX3451E variant if internal enumeration functionality is required, or the MAX3452E if bus detection outputs are necessary. Ensure the system power supply accommodates the specified VL and VBUS ranges.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX3450E/MAX3451E/MAX3452E family of USB transceivers manufactured by Analog Devices / Maxim Integrated. These devices share similar core functionalities but differ in specific features like enumeration and bus detection. The MAX3450E serves as the base model in this series, offering pin compatibility with Micrel’s MIC2550A.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX3450E is pin compatible with Micrel’s MIC2550A. Verify electrical specifications and feature sets before substituting with other USB transceivers from different manufacturers.
