The Intersil ISL54233 is a single supply differential 3 to 1 multiplexer 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 data signals, UART data signals and digital video through a common headphone connector in Personal Media Players and other portable battery powered devices. The switch channels have low ON capacitance and high bandwidth (1. 6GHz) to pass USB high speed signals (480Mbps) and digital video signals with minimal edge and phase distortion and can swing rail-to-rail to pass UART and full-speed USB signals. All channels of the multiplexer can be turned OFF (disabled) by driving the C0 and C1 logic pins to the low state. The ISL54233 is available in a tiny 12 Ld 2. 2mmx1. 4mm ultra-thin QFN and 12 Ld 3mmx3mm TQFN package. It operates over a temperature range of -40°C to +85°C.
