DATASHEET ISL54216 FN7701 Rev.1.00 USB 2.0 High-Speed/UART Dual SP3T (Dual 3 to 1 Multiplexer) Dec 5, 2018 The ISL54216 is a single supply dual SP3T analog Features switch that operates from a single supply in the range High Speed (480Mbps) and Full Speed (12Mbps) of 2.7V to 4.6V. It was designed to multiplex between Signaling Capability per USB 2.0 on All Ports three different differential data sources, allowing the multiplexing of USB 2.0 high speed and/or UART data UART Capability on All Ports signals through a common headphone connector in COM Pins Allow Negative Swings to -2V Personal Media Players and other portable battery Compatible with Wired-OR Connected GND powered devices. Referenced Audio Sources The switch channels have very low ON capacitance All Switches Open Mode and high bandwidth to pass USB high speed signals Power OFF Protection (480Mbps) with minimal edge and phase distortion and can swing rail-to-rail to pass UART and full-speed COM Pins Overvoltage Tolerant to 5.5V USB signals. Low ON Capacitance 240MHz 4pF The ISL54216 is available in a tiny 12 Ld -3dB Frequency 800MHz 2.2mmx1.4mm ultra-thin QFN and 12 Ld 3mmx3mm Single Supply Operation (V )2.7V to 4.6V DD TQFN packages. It operates over a temperature range Available 12 Ld TQFN and 12 Ld TQFN Packages of -40C to +85C.
