USB1T11AMX

Overview

The USB1T11AMX is a single-channel USB 2.0 transceiver manufactured by onsemi, designed for interface applications between standard logic and the Universal Serial Bus physical layer. It supports full-speed data rates of 12 Mbit/s and low-speed rates of 1.5 Mbit/s. The device operates with supply voltages of 3.3V or 5.0V and features half-duplex communication. Packaged in a 14-lead Small Outline Integrated Circuit (SOIC) with tape and reel packaging, it functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides electrical isolation and signal conversion between host controller logic levels and USB differential signaling lines.
• Supports both full-speed and low-speed data transmission modes compliant with USB specifications.
• Integrates necessary drivers and receivers for single-channel bidirectional data flow.

Applications

• Peripheral devices such as printers and scanners
• Digital cameras and other consumer electronics
• General-purpose USB interface circuits requiring 3.3V or 5.0V operation

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm package integrity upon receipt, as tape-and-reel units require specific handling equipment. Check manufacturing date codes against project timelines to ensure compatibility with current assembly processes. Validate RoHS compliance status if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when interfacing 3.3V or 5.0V logic systems with USB ports requiring half-duplex communication. Ensure the design accommodates the 14-pin SOIC footprint and thermal requirements for the specified industrial temperature range. Consider availability constraints as older interface components may have limited long-term supply guarantees compared to newer integrated solutions.

Part Context

This part belongs to the USB1T11 family of universal serial bus transceivers from onsemi. It serves as a bridge between microcontroller-based systems and USB peripherals. The AMX suffix indicates the specific tape-and-reel packaging variant, distinguishing it from tube-packaged versions like the AMTC. It represents a standard solution for legacy or cost-sensitive USB implementations.

Replacement Considerations

Direct substitutes include other single-channel USB transceivers with compatible pinouts and voltage ranges. Verify that alternative parts support the same 12Mbps and 1.5Mbps data rates. Ensure the replacement maintains the 14-pin SOIC form factor to fit existing PCB layouts without redesigning the board traces or mounting holes.
