DATASHEET ISL54217 FN6817 Rev.5.00 Dec 12, 2018 USB 2.0 High-Speed x 2 Channels/Stereo Audio Dual SP3T (Dual 3-to-1 Multiplexer) Features The ISL54217 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 audio stereo signals and two different USB 2.0 high speed differential data signals. The audio channels allow signal swings below ground, allowing the multiplexing of voice and data signals through a common headphone connector in Personal Media Players and other portable battery powered devices. • High Speed (480Mbps) and Full Speed (12Mbps) Signaling Capability per USB 2.0 • Low Distortion Negative Signal Capability Audio Switches • Clickless/Popless Audio Switches • Power OFF Protection • COM Pins Overvoltage Tolerant to 5.5V The audio switch cells can pass ±1V ground referenced audio signals with very low distortion (500V . . >2kV at 85°C CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and result in failures not covered by warranty. NOTES: 6. Signals on C1 and C0 exceeding GND by specified amount are clamped. Limit current to maximum current ratings. 7. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details. 8. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See Tech Brief TB379. 9. For JC, the “case temp” location is the center of the exposed metal pad on the package underside. 10. For JC, the “case temp” location is taken at the package top center.

It operates from a single DC power supply in the range of 2.7V to 4.6V. It was designed to function as differential 3-to-1 multiplexer to select between two different USB differential data signals and audio L and R stereo signals. It comes in a tiny µTQFN and TQFN packages for use in FN6817 Rev.5.00 Dec 12, 2018 MP3 players, PDAs, cell phones, and other personal media players. A device consists of two 2.3 audio switches and four 6.2 USB switches. The audio switches can accept signals that swing below ground. They were designed to pass audio left and right stereo signals, that are ground referenced, with minimal distortion. The USB switches were designed to pass high-speed USB differential data signals with minimal edge and phase distortion. Page 11 of 25 ISL54217 The ISL54217 was specifically designed for MP3 players, personal media players and cellphone applications that need to combine the stereo audio and USB data channels into a single shared connector, thereby saving space and component cost. The “Block Diagram” of this functionality is shown on page 11. The ISL54217 contains two logic control pins (C1 and C0) that determine the state of the device. The part has the following five states or modes of operation: All SWITCHES OFF; USB1; USB2; Audio; and Audio Mute. These states are discussed in detail in “Logic Control” on page 12. A detailed description of the various types of switches are provided in “Audio Switches” beginning on page 12. Audio Switches The two audio switches (L, R) are 2.3 switches that can pass signals that swing below ground. Over a signal range of ±1V (0.707VRMS) with VDD > 2.7V, these switches have an extremely low rON resistance variation. They can pass ground referenced audio signals with very low distortion ( Audio (C1 = 1, C0 =1) Audio (C1 = 1, C0 = 1) -----> All OFF (C1 = 0, C0 = 0) Audio Mute (C1 = 1, C0 = 0) ---> USB1 (C1 = 0, C0 = 1) The audio L and R click and pop shunt circuitry will be activated and the 1k COM shunt resistors will be disconnected (OFF). The delay time between transition of these bits must be
