Maxim Integrated MAX4840EX High-Speed USB 2.0 Switch

The MAX4840EX from Maxim Integrated is a high-performance, high-speed USB 2.0 analog switch specifically designed to enable USB 2.0 applications with minimal signal distortion and attenuation. This switch is an ideal choice for applications requiring the routing of high-speed differential signals with bandwidths up to 480Mbps.

The MAX4840EX features low on-capacitance (C<sub>ON) and on-resistance (R<sub>ON), ensuring that the signal integrity is maintained during transmission. The low R<sub>ON also helps to minimize voltage drop across the switch, which is crucial for maintaining signal levels within the USB specification limits.

With a single supply voltage ranging from 2.7V to 3.6V, the MAX4840EX is versatile and can be easily integrated into various USB-powered devices. Its single control input (CTL) allows for simple operation; a high level on CTL turns the switch on, while a low level turns it off. This control feature simplifies the design and reduces the complexity of the control logic required.

The MAX4840EX offers enhanced electrostatic discharge (ESD) protection for the USB data lines, which is essential for safeguarding the device against static damage during handling and connection/disconnection events. The integrated ESD protection circuits can withstand up to ±15kV air-gap and ±8kV contact discharges, as specified in the IEC 61000-4-2 standard.

Available in a small, space-saving 6-pin SC70 package or 6-bump UCSP™, the MAX4840EX is perfect for portable applications where board space is at a premium. Its compact form factor makes it an excellent choice for use in USB hubs, docking stations, peripherals, and any other application that requires switching of high-speed USB signals.

Overall, the Maxim Integrated MAX4840EX switch provides a reliable, high-speed USB 2.0 switching solution that enhances the performance and durability of USB systems while maintaining signal integrity and ease of use.
