DATASHEET ISL54217 FN6817 Rev.5.00 USB 2.0 High-Speed x 2 Channels/Stereo Audio Dual SP3T (Dual 3-to-1 Dec 12, 2018 Multiplexer) The ISL54217 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 audio stereo signals and two different USB 2.0 high speed differential data signals. The audio channels Low Distortion Negative Signal Capability Audio allow signal swings below ground, allowing the Switches multiplexing of voice and data signals through a Clickless/Popless Audio Switches common headphone connector in Personal Media Power OFF Protection Players and other portable battery powered devices. COM Pins Overvoltage Tolerant to 5.5V The audio switch cells can pass 1V ground Low Distortion Headphone Audio Signals referenced audio signals with very low distortion - THD+N at 5mW into 32Load . <0.03% (<0.03% THD+N when driving 5mW into 32 loads). The USB switch cells have very low ON-capacitance Crosstalk (100kHz) . -98dB (8pF) and high bandwidth to pass USB high speed OFF-Isolation (100kHz) . 95.5dB signals (480Mbps) with minimal edge and phase distortion. Single Supply Operation (V ) . 2.7V to 4.6V DD -3dB Bandwidth USB Switches . 700MHz The ISL54217 is available in a tiny 12 Ld 2.2mmx1.4mm ultra thin QFN and a 12 Ld Available in Tiny 12 Ld TQFN and TQFN Packages 3mmx3mm TQFN package. It operates over a Compliant with USB 2.0 Short Circuit temperature range of -40C to +85C.
