Analog Switches - Special Purpose datasheet and documents for FSUSB30L10X
Analog Switches - Special Purpose Overview
The FSUSB30L10X is a low-power, dual-port, high-speed USB 2.0 switch IC manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a single supply voltage range of 3V to 4.3V and features a -3dB bandwidth of 720MHz. The device utilizes a 10-MicroPak™ package (10-UFQFN with exposed pad) and supports DPDT switching circuits. Key electrical specifications include a maximum on-resistance of 10 ohms and an operating temperature range from -40°C to +85°C. The component is RoHS compliant and designated as obsolete.
Analog Switches - Special Purpose Feature Summary
- Supports USB 2.0 high-speed data transmission up to 480Mbps
- Features break-before-make switching logic for signal integrity
- Designed for low power consumption in portable applications
Analog Switches - Special Purpose Applications
- USB hub implementations
- Portable electronic devices requiring USB connectivity management
- Computer peripherals with USB interface requirements
Analog Switches - Special Purpose Procurement Notes
Verify the obsolete status indicated in public records before initiating any procurement process. Confirm that the current manufacturer, onsemi, accepts the legacy part number designation. Ensure compliance with RoHS3 standards if required by the target market regulations. Check for any specific PCN notices regarding material or packaging changes prior to finalizing orders.
Analog Switches - Special Purpose Selection Notes
Select this component when a compact, low-power USB 2.0 switch is required for dual-port configurations. The 10-MicroPak package suits space-constrained designs. Verify that the 3V to 4.3V supply range aligns with the system's power architecture. Consider the 10-ohm on-resistance impact on signal performance for the specific application path.
Analog Switches - Special Purpose Part Context
This component belongs to the FSUSB30 series of USB switches originally developed by Fairchild Semiconductor. Following the acquisition and integration into onsemi, the product line continues under the new manufacturer identity. The part represents a legacy solution for high-speed USB switching in consumer electronics, now marked as end-of-life in distributor databases.
Analog Switches - Special Purpose Replacement Considerations
Public records list the FSUSB43L10X as a similar substitute from onsemi. The TS3USB3000MRSER from Texas Instruments is also identified as a comparable alternative. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
