UM7227

Overview

The UM7227 is a dual-port, high-speed, low-power data switch optimized for USB 2.0 signal switching applications. Manufactured by Union Semiconductor International Limited, this integrated circuit functions as a double-pole/double-throw (DPDT) analog switch. It supports bidirectional signal flow and features a -3dB bandwidth of 750 MHz. The device operates within a voltage range of 1.8V to 4.3V, making it suitable for mobile phones and consumer electronics requiring efficient signal routing with minimal power consumption.

Feature Summary

Configured as a double-pole/double-throw (DPDT) switch for flexible signal routing
Optimized specifically for high-speed USB 2.0 signal switching applications
Supports bidirectional signal flow with a -3dB bandwidth of 750 MHz
Operates on a low voltage supply ranging from 1.8V to 4.3V

Applications

Mobile phone signal switching
Consumer electronic device interfaces
USB 2.0 port protection and routing

Procurement Notes

Verify the specific suffix variant (QA or MA) required for your design, as these denote package or temperature grade differences. Confirm the operating voltage range aligns with your system's power rails. Ensure ESD handling procedures are followed during assembly. Check that the DPDT configuration meets your signal path requirements. Validate compatibility with USB 2.0 specifications before final integration.

Selection Notes

Choose the UM7227 when designing circuits requiring high-speed data switching for USB 2.0 interfaces. Its 750 MHz bandwidth ensures signal integrity for high-frequency data transmission. The low-power operation makes it ideal for battery-powered devices. Consider the DPDT topology if bidirectional switching between two ports is necessary. Verify the 1.8V to 4.3V supply range matches your application's voltage constraints.
