1 19-75; Rv 0; 7/0 ABRIDGED DATA SHEET Gnral Dscription Th family of dual SPDT (singl-pol/doubl-throw) switchs oprat from a singl +V to +5.5V supply and can handl signals gratr than th supply rail. Ths switchs fatur low.5ω or.5ω/7ω on-rsistanc with low oncapacitanc, making thm idal for switching audio and data signals. Th MAX850/MAX850H ar configurd with two SPDT switchs and fatur two comparators for hadphon dtction or mut/snd ky functions. Th MAX85 has two SPDT switchs with no comparators for low 1µA supply currnt. For ovr-rail applications, ths dvics offr ithr th pass-through or high-impdanc option. For th MAX850/MAX85, th signal (up to 5.5V) passs through th switch without distortion vn whn th positiv supply rail is xcdd. For th MAX850H/ MAX85H, th switch input bcoms high impdanc whn th input signal xcds th supply rail. Th ar availabl in th spac-saving (mm x mm), 16-pin TQFN packag and oprat ovr th xtndd tmpratur rang of -0 C to +85 C.

2 Dtaild Dscription Th ar low on-rsistanc, low-voltag, analog switchs that oprat from a +V to +5.5V singl supply and ar fully spcifid for nominal. applications. Ths dvics fatur ovr-rail signal capability that allows signals up to 5.5V with supply voltags down to.. Ths dvics ar configurd as dual SPDT switchs. Ths switchs hav low 50pF on-channl capacitanc, which allows for 1Mbps switching of th data signals for USB.0 full spd/1.1 applications. Th MAX85 ar dsignd to switch D+ and D- USB signals with a guarantd skw of lss than 1ns (s Figur 1), as masurd from of th input signal to of th output signal. Th fatur a comparator that can b usd for hadphon or mut dtction. Th comparator thrshold is intrnally gnratd to b approximatly 1/ of. Applications Information Digital Control Inputs Th logic inputs () accpt up to +5.5V vn if th supply voltags ar blow this lvl. For xampl, with a +.V supply, can b drivn low to and high to +5.5V, allowing for mixing of logic lvls in a systm. Driving rail-to-rail minimizs powr consumption. For a +V supply voltag, th logic thrsholds ar 0.5V (low) and 1.V (high); for a +5V supply voltag, th logic thrsholds ar 0.8V (low) and 1.8V (high). Analog Signal vls Th on-rsistanc of ths switchs changs vry littl for analog input signals across th ntir supply voltag rang (s Typical Oprating Charactristics). Th switchs ar bidirctional, so, NC_, and can b ithr inputs or outputs. Comparator Th positiv trminal of th comparator is intrnally st to /. Whn th ngativ trminal (C) is blow th thrshold ( /), th comparator output (COUT_) gos high. Whn C riss abov /, COUT_ gos low. Th comparator thrshold allows for dtction of hadphons sinc hadphon audio signals ar typically biasd to /. Powr-Supply Squncing Caution: Do not xcd th absolut maximum ratings bcaus strsss byond th listd ratings may caus prmannt damag to th dvic. Propr powr-supply squncing is rcommndd for all CMOS dvics. Always apply bfor applying analog signals, spcially if th analog signal is not currnt-limitd. 11
