Chithunzi cha SN65HVD485EDR RS-485 IC Half-Duplex RS-485 Transceiver

Chipangizo cha SN65HVD485E ndi transceiver ya theka-duplex yopangidwira ma RS-485 data bus network. Mothandizidwa ndi 5-V, ​​imagwirizana kwathunthu ndi muyezo wa TIA/EIA-485A. Chipangizochi ndi choyenera kutumizira ma data mpaka 10 Mbps pazingwe zazitali zopotoka ndipo chimapangidwa kuti zizigwira ntchito ndi zotsika kwambiri, nthawi zambiri zosakwana 2 mA, kupatula katunduyo. Chidacho chikakhala chotsekeka, mphamvu yamagetsi imatsika pansi pa 1 mA.
Kutalikirana kwamitundu yodziwika bwino komanso chitetezo chambiri cha ESD cha chipangizochi chimapangitsa kuti chikhale choyenera kugwiritsa ntchito zinthu zambiri monga: zosinthira zamagetsi, ma siginecha amtundu uliwonse pa telecom racks, zolumikizirana ndi ma chassis, ndi ma network automation a mafakitale komwe kulekerera phokoso ndikofunikira. Chipangizo cha SN65HVD485E chikufanana ndi zomwe zidachitika pakampani ya SN75176. Mabwalo obwezeretsanso mphamvu amasunga zotuluka m'malo osavutikira kwambiri mpaka magetsi operekera akhazikika. Kuzimitsa kwa kutentha kumateteza chipangizo kuti zisawonongeke chifukwa cha vuto la dongosolo. Chipangizo cha SN65HVD485E chimadziwika kuti chizigwira ntchito kuchokera -40 ° C mpaka 85 ° C kutentha kwa mpweya.
