? semiconductor components industries, llc, 2010 june, 2010 ? rev. 1 1 publication order number: ncn1154/d ncn1154 dp3t usb 2.0 high speed / audio switch with negative swing capability the ncn1154 is a dp3t switch for combined true ? ground audio, usb 2.0 high speed data, and uart applications. it allows portable systems to use a single port to pass either usb data or audio signals from an external headset. the switch is capable of passing signals with negative voltages as low as 2 v below ground. the ncn1154 features shunt resistors on the audio ports. these resistors are switched in when the audio channel is off and provide a safe path to ground for any charge that may build up on the audio lines. this reduces pop & click noise in the audio system. the device has an extended v cc range which can operate off v cc up to 4.2 v while passing true ground audio signals down to ? 2 v. features ? 480 mbps high speed usb capable ? capable of passing negative swing signals down to ? 2 v ? 1.8 v compatible control pins for 2.7 v v cc 4.2 v ? high usb path bandwidth (850 mhz) ? usb/audio/uart ? audio channel shunt resistors for pop & click noise reduction ? ultra low thd in audio mode: 0.01% into 16 load ? 5.25 v tolerant common pins ? this is a pb ? free device typical applications ? shared usb/uart/audio connector ? mobile phones ? portable devices http://onsemi.com uqfn12 mu suffix case 523ae marking diagram device package shipping ? ordering information NCN1154MUTAG uqfn12 (pb ? free) 3000 / tape & reel application diagram ?for information on tape and reel specifications, including part orientation and tape sizes, please refer to our tape and reel packaging specification brochure, brd8011/d. ac = specific device code m = date code = pb ? free package acm 1 ncn1154 usb connector com+ com ? d+ d ? rx tx r l in1, in2 from baseband hs usb xcvr uart xcvr true gnd audio
