♠ I-SN65HVD178x iFault-Protected RS-485 Transceivers With 3.3-V to 5-V Operation
Izixhobo ze-SN65HVD178x ziyilelwe ukuba ziphile kwiimpazamo zombane ogqithisileyo onje ngeeshoti ezithe ngqo kumbane, iimpazamo ze-mis-wiring, ukungaphumeleli kwesinxibelelanisi, ukutyunyuzwa kweentambo, kunye nezixhobo ezingafanelekanga.Izixhobo zikwanamandla kwiziganeko ze-ESD ezinamazinga aphezulu okukhusela kwinkcazo yemodeli yomntu.
Izixhobo ze-SN65HVD178x zidibanisa umqhubi ohlukeneyo kunye nommkeli ohlukeneyo, osebenza kumbane omnye.Kwi-SN65HVD1782, iziphumo zokwahlukana komqhubi kunye neengeniso ezihlukeneyo zomamkeli zixhunywe ngaphakathi ukuze zenze i-bus port efanelekile kwi-half-duplex (ii-wire-wire bus) zonxibelelwano.Eli zibuko libonisa uluhlu olubanzi lwamandla ombane oqhelekileyo, okwenza izixhobo zilungele usetyenziso lwee-multipoint ngaphezulu kweentambo ezinde.Ezi zixhobo ziphawulwa ukusuka ku-40°C ukuya kwi-125°C.
Ezi zixhobo zi-pin-zihambelana ne-transceiver ye-SN75176 ye-industrystandard, ezenza ukuba zihlaziywe kwiinkqubo ezininzi.Ezi zixhobo zihambelana ngokupheleleyo ne-ANSI TIA / EIA 485-A kunye ne-5-V yokubonelela kwaye ingasebenza kunye nokunikezelwa kwe-3.3-V kunye nokunciphisa umbane wokukhupha umqhubi kwizicelo zamandla aphantsi.Ukulungiselela usetyenziso apho kufuneka umsebenzi kuluhlu olwandisiweyo lwamandla ombane wemowudi eqhelekileyo, bona i-SN65HVD1785 (SLLS872) kwiphepha ledatha.
