TSU6111ARSVR

Overview

The TSU6111ARSVR is a USB port SP2T switch manufactured by Texas Instruments, designed to support USB and UART interfaces. It features an integrated impedance detection mechanism for automatic path selection. The device operates within a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a maximum on-resistance of 30 ohms and a maximum leakage current of 1 nA. The component supports a data rate up to 480 Mbps and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrated impedance detection for automatic switching between USB and UART paths
• Supports high-speed data transmission up to 480 Mbps
• Low leakage current ensures minimal power consumption in standby mode

Applications

• Micro-USB host ports requiring dual-path connectivity
• UART interface multiplexing in embedded systems
• Portable electronic devices with mixed communication interfaces

Procurement Notes

Verify the specific suffix ARSVR against the official datasheet to confirm package type and tape/reel specifications. Ensure compatibility with your PCB footprint and reflow profile requirements before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require automatic switching between USB host and UART debug interfaces. Verify that the required data rate does not exceed 480 Mbps and that the supply voltage aligns with the 2.7 V to 5.5 V operational range.

Part Context

This part belongs to the TSU6111 family of USB switches from Texas Instruments. It is specifically engineered for applications needing seamless integration of USB and UART signals within a compact form factor, often found in mobile and industrial control hardware.
