Overview
The UM7222MA is a high-speed USB 2.0 (480 Mbps) DPDT switch manufactured by Union Semiconductor, Inc. It functions as an analog switch designed for two-port applications in USB 2.0 systems. The component supports data transmission rates up to 480 Mbps, enabling efficient signal routing between connected devices. As a dual-pole double-throw switch, it provides flexible connectivity options for managing multiple USB ports within a single integrated circuit package.
Feature Summary
- Supports high-speed USB 2.0 data transmission at 480 Mbps
- Configured as a dual-pole double-throw (DPDT) analog switch
- Designed for two-port USB application management
Applications
- USB 2.0 port switching and routing
- Dual-port USB connectivity management
- High-speed data signal path selection
Part Context
The UM7222MA belongs to the UM7222 series of high-speed USB switches from Union Semiconductor. This series includes variants such as the UM7222 and UM7222A, all sharing the core function of handling 480 Mbps USB 2.0 signals. The MA suffix typically denotes specific packaging or tape-and-reel configuration details rather than functional changes, consistent with industry standard naming conventions for this manufacturer's switch family.
Replacement Considerations
Publicly confirmed substitute part numbers include Vishay Siliconix DG2720, DG2722, and DG2730, which are also 2-port USB 2.0 high-speed DPDT analog switches. Other potential equivalents found in public documentation include KEC KUSB50QN and Alpha & Omega Semiconductor AOZ6186 and AOZ6184. Verification of pin compatibility and electrical specifications against official datasheets is required before substitution.
