TS5USBC412YFFR

Overview

The TS5USBC412YFFR is a USB interface integrated circuit manufactured by Texas Instruments, belonging to the TS5USBC41 series. It functions as a dual 2:1 USB 2.0 multiplexer/demultiplexer or a single enabled switch. The device supports High Speed (HS) data rates compliant with USB 2.0 standards and features a 1.1 GHz -3dB bandwidth. It operates within a supply voltage range of 2.3 V to 5.5 V, typically at 3.3 V, with a low operating supply current of 9 uA. The component is housed in a compact 12-DSBGA package and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

• Dual-channel architecture enabling flexible routing between two sources and one destination or vice versa.
• Supports bidirectional signal transmission compatible with USB 2.0 specifications.
• Low power consumption design suitable for battery-operated portable devices.

Applications

• USB port expansion in mobile handsets and tablets
• Connecting multiple USB peripherals to a single host controller
• UART signal switching in embedded systems

Procurement Notes

Verify the specific suffix YFFR confirms the reel packaging format when ordering. Confirm the commercial temperature grade (0°C to 70°C) meets system requirements, as other variants may support extended industrial ranges. Ensure the 12-DSBGA footprint matches the PCB layout guidelines provided in the official datasheet to guarantee proper soldering and thermal performance during assembly.

Selection Notes

Select this component when a dual-channel USB 2.0 mux/demux solution is required in a minimal footprint. Compare against the TS5USBC410YFFR if different pin configurations or specific enable logic are needed. Verify that the 9 uA quiescent current aligns with the system's power management strategy. Ensure the 1.1 GHz bandwidth is sufficient for the intended High Speed data rates without significant signal degradation.

Part Context

This part belongs to the TS5USBC41 family of USB switches from Texas Instruments. It shares core technology with models like the TS5USBC412IYFFT but differs in packaging and potentially temperature ratings. The DSBGA-12 package allows for space-constrained designs common in modern consumer electronics. It serves as a critical interconnect component for managing USB connectivity in compact devices.

Replacement Considerations

The TS5USBC412IYFFT is a related variant within the same family. Verify if the industrial temperature rating (-40°C to 85°C) of the IYFFT variant is necessary for the application. Check pin-to-pin compatibility and electrical parameter equivalence before substitution.
