MAX3346EEUD+T

Overview

The MAX3346EEUD+T is a USB On-The-Go (OTG) transceiver compliant with the USB 2.0 specification, supporting High Speed data rates up to 480 Mb/s and Full Speed at 12 Mb/s. It operates on dual power supplies: VCCIO ranging from 1.65 V to 3.6 V and VBUS from 4 V to 5.5 V. The device features integrated ESD protection rated at 15 kV for human body model applications. Packaged in a 14-pin TSSOP, it draws a maximum operating supply current of 8 mA. This component facilitates direct connection between USB host and peripheral functions in portable electronics.

Feature Summary

• Integrates OTG transceiver functionality with full USB 2.0 protocol compliance
• Provides robust 15 kV ESD protection on all I/O pins
• Supports both High Speed (480 Mb/s) and Full Speed (12 Mb/s) data transfers
• Operates with low-voltage logic interfaces and standard USB bus voltages

Applications

• Portable computing devices requiring host/peripheral switching
• Digital cameras and multimedia peripherals
• Mobile communication handsets
• USB flash drives and external storage media

Procurement Notes

Verify the complete part number including the +T suffix to confirm tape-and-reel packaging configuration. Ensure compatibility with the target system's voltage domains, specifically the 1.65 V to 3.6 V IO supply and 4 V to 5.5 V VBUS requirements. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when designing systems requiring bidirectional USB connectivity without external multiplexing switches. The integrated ESD protection reduces bill-of-materials complexity compared to standard transceivers. Verify that the application environment stays within the specified -40°C to +85°C operating temperature range and that the TSSOP-14 package footprint aligns with the PCB layout constraints.

Part Context

This device belongs to the MAX3346E series of USB interface integrated circuits manufactured by Analog Devices / Maxim Integrated. It serves as a specialized solution for OTG applications, distinguishing itself from standard host or device-only transceivers by managing role negotiation hardware signals internally.
