♠ SN65HVD178x Zotetezedwa Zotetezedwa za RS-485 Zogwiritsa Ntchito 3.3-V mpaka 5-V
Zipangizo za SN65HVD178x zidapangidwa kuti zisamawonongeke ndi kuwonongeka kwamagetsi ochulukirapo monga akabudula achindunji kumagetsi, zolakwika za ma wiring, kulephera kwa zolumikizira, kuphwanya zingwe, ndi kugwiritsa ntchito molakwika zida. Zidazi zimakhalanso zolimba ku zochitika za ESD zokhala ndi chitetezo chokwanira pamafotokozedwe amtundu wamunthu.
Zipangizo za SN65HVD178x zimaphatikiza dalaivala wosiyana ndi cholandila chosiyana, chomwe chimagwira ntchito kuchokera kumagetsi amodzi. Mu SN65HVD1782, zotulutsa zosiyanitsira madalaivala ndi zolowera zosiyanitsira zimalumikizidwa mkati kuti apange doko loyenera kulumikizana ndi theka-duplex (mabasi a waya awiri). Doko ili limakhala ndi mitundu yambiri yamagetsi yamtundu wa commonmode, zomwe zimapangitsa kuti zidazo zikhale zoyenera kugwiritsa ntchito ma multipoint pazingwe zazitali. Zida izi zimadziwika kuchokera -40 ° C mpaka 125 ° C.
Zipangizozi zimagwirizana ndi ma transceiver a SN75176, zomwe zimawapangitsa kukhala otsika pamakina ambiri. Zipangizozi zimagwirizana kwathunthu ndi ANSI TIA/EIA 485-A yokhala ndi 5-V ndipo imatha kugwira ntchito ndi 3.3-V yokhala ndi mphamvu yocheperako yotulutsa madalaivala pazogwiritsa ntchito mphamvu zochepa. Pamapulogalamu omwe amafunikira ma voliyumu amtundu wamba, onani SN65HVD1785 (SLLS872) data sheet.
