ON Semiconductor FSUSB23BQX USB 2.0 High-Speed Switch

The FSUSB23BQX from ON Semiconductor is a high-performance, dual single-pole double-throw (SPDT) switch specifically designed for USB 2.0 high-speed applications. It operates as a multiplexer/demultiplexer for differential signals, making it an ideal choice for a range of consumer electronics, including smartphones, tablets, and laptops, as well as desktop computers and peripheral devices.

This advanced switch is optimized for low bit-to-bit skew, high channel-to-channel noise isolation, and is compatible with high-speed (480 Mbps) and full-speed (12 Mbps) signaling. Its low on-capacitance (C<sub>on) and low on-resistance (R<sub>on) ensure minimal signal distortion and attenuation, providing a reliable and efficient signal routing solution for USB data lines.

Key features of the FSUSB23BQX include:

• Low power consumption, which is critical for battery-powered devices.
• Extended -40°C to +85°C operating temperature range, suitable for various environmental conditions.
• 5V tolerant logic inputs, which allow for direct connection to a variety of logic levels.
• High bandwidth (720 MHz) that accommodates the fast data rates of USB 2.0.
• ESD protection on all pins (±8 kV Contact, ±15 kV Air), enhancing the durability and reliability of the device.

The FSUSB23BQX comes in an ultra-compact μQFN-10 package, which is designed to save board space and is ideal for space-constrained applications. Its small form factor coupled with the low power consumption makes it a practical solution for portable electronic devices where size and battery life are critical.

Integrating the FSUSB23BQX into your design is straightforward, thanks to its industry-standard pinout and compatibility with existing USB 2.0 interfaces. Whether you are designing a new product or upgrading an existing one, the FSUSB23BQX offers a perfect balance of performance, power efficiency, and miniaturization, making it an excellent choice for your USB switching needs.
