The Intersil ISL54206A dual SPDT (Single Pole/DoubleThrow) switches combine low distorTIon audio and accurateUSB 2.0 high speed data (480Mbps) signal switching in thesame low voltage device. When operated with a 2.7V to 3.6Vsingle supply these analog switches allow audio signalswings below-ground, allowing the use of a common USBand audio headphone connector in Personal Media Playersand other portable battery powered devices.The ISL54206A logic control pins are 1.8V compaTIble whichallows for control via a standard μcontroller. With a VDDvoltage in the range of 2.7V to 3.6V the IN pin voltage canexceed the VDD rail allowing for the USB 5V VBUS voltagefrom a computer to directly drive the IN pin to switchbetween the audio and USB signal sources in the portabledevice. The part has an audio enable control pin to open allthe switches and put the part in a low power state.The ISL54206A is available in a small 10 Ld 2.1mmx1.6mmultra-thin μTQFN package and a 10 Ld 3mmx3mm TDFNpackage. It operates over a temperature range of -40 to +85°C.
