♠ I-SN65HVD178x I-Fault-Protected RS-485 Transceivers With 3.3-V to 5-V Operation
Amadivayisi e-SN65HVD178x adizayinelwe ukuthi asinde emaphutheni e-overvoltage njengezikhindi eziqondile ezinikezwa amandla, amaphutha e-mis-wiring, ukwehluleka kwezixhumi, ukuchotshozwa kwekhebula, nokusetshenziswa kabi kwamathuluzi. Amadivayisi aphinde aqine emicimbini ye-ESD enamazinga aphezulu okuvikela ekucacisweni kwemodeli yomuntu-yomzimba.
Amadivayisi we-SN65HVD178x ahlanganisa umshayeli ohlukile kanye nomamukeli ohlukile, osebenza kusukela ekunikezeni amandla okukodwa. Ku-SN65HVD1782, okokufaka okuhlukile komshayeli nokokufaka okuhlukile kowamukelayo kuxhunywa ngaphakathi ukwenza ichweba lebhasi elifanele ukuxhumana kwe-half-duplex (ibhasi lezintambo ezimbili). Lesi sikhumulo sinobubanzi be-voltage yemodi evamile, okwenza amadivaysi afanele ukusetshenziswa kwama-multipoint phezu kokusebenza kwekhebula okude. Lezi zisetshenziswa zihlukaniswa ukusuka ku -40°C kuya ku-125°C.
Lawa madivayisi ahambisana nephinikhodi ne-transceiver ejwayelekile yemboni ye-SN75176, okuwenza abe ukuthuthukiswa kokungena kumasistimu amaningi. Lawa madivayisi athobelana ngokugcwele ne-ANSI TIA/EIA 485-A enokunikezwa okungu-5-V futhi angasebenza ngokunikezwa okungu-3.3-V okunogesi ophumayo womshayeli oncishisiwe wezinhlelo zokusebenza zamandla amancane. Mayelana nezinhlelo zokusebenza lapho kudingeka khona ukusebenza ebangeni elinwetshiwe lemodi evamile yamandla kagesi, bona i-SN65HVD1785 (SLLS872) ishidi ledatha.
