The Intersil ISL54216 is a single supply dual SP3T analog switch that operates from a single supply in the range of 2. 7V to 4. 6V. It was designed to multiplex between three different differential data sources, allowing the multiplexing of USB 2. 0 high speed and/or UART data signals through a common headphone connector in Personal Media Players and other portable battery powered devices. The switch channels have very low ON capacitance and high bandwidth to pass USB high speed signals (480Mbps) with minimal edge and phase distortion and can swing rail-to-rail to pass UART and full-speed USB signals. The ISL54216 is available in a tiny 12 Ld 2. 2mmx1. 4mm ultra-thin QFN and 12 Ld 3mmx3mm TQFN packages. It operates over a temperature range of -40°C to +85°C.
