Kev tsis
DS1487M RS-485 transceiver yog ib qho kev daws teeb meem thiab muaj zog rau kev sib txuas lus ntau, ua raws li TIA/EIA RS-485 tus qauv. Nrog kev txhawb nqa txog li 128 transceivers ntawm lub tsheb npav, lav tag nrho cov khoom tso tawm hluav taws xob, tsis tshua muaj hluav taws xob tam sim no, thiab ntau hom kev tawm tswv yim voltage ntau, nws ua tau zoo hauv cov ntawv thov kev lag luam. TRI-STATE outputs, AC kev ntsuas kev ua tau zoo, ib nrab-duplex ntws-los ntawm pinout, thiab ib qho 5V muab kev ua haujlwm pab txhawb rau nws cov txiaj ntsig thiab kev yooj yim ntawm kev koom ua ke. Cov yam ntxwv ntxiv xws li kev txwv tam sim no, thermal kaw, thiab kev sib raug zoo nrog MAX1487 ntxiv txhim kho nws txoj kev ntseeg tau thiab siv tau hauv qhov xav tau ib puag ncig. DS1487M yog cov khoom siv dav dav thiab kev ua haujlwm siab, tsim kom muaj kev sib txuas lus zoo.

General Description:
DS1487 yog lub tshuab hluav taws xob qis rau RS-485 thiab RS-422 kev sib txuas lus. Cov cuab yeej muaj ib tus tsav tsheb thiab ib tus txais. Tus neeg tsav tsheb slew tus nqi tso cai rau kev ua haujlwm txog li 2.0 Mbps (saib Daim Ntawv Qhia Cov Ntaub Ntawv Ntu). Lub transceiver nthuav tawm 1⁄4 chav tsev thauj khoom mus rau RS -485 tsheb npav uas tso cai rau 128 ntawm kev sib txuas ua ke yam tsis tas siv cov rov ua dua.
Lub transceiver rub tawm 200 µA ntawm cov khoom siv tam sim no thaum thauj khoom lossis thauj tag nrho nrog tus neeg tsav tsheb tsis taus thiab ua haujlwm los ntawm ib qho +5V muab. Tus neeg tsav tsheb yog luv luv-circuit tam sim no txwv thiab tiv thaiv cov hluav taws xob ntau dhau los ntawm thermal shutdown circuitry uas tso tus neeg tsav tsheb tso rau hauv TRI-STATE® (High Impedance state) nyob rau hauv qhov teeb meem txhaum cai. Tus neeg tsav tsheb lav qhov tsawg kawg nkaus ntawm 1.5V qhov sib txawv ntawm qhov tso zis hluav taws xob nrog qhov siab tshaj plaws thauj khoom hla ntau hom hom (VOD3).
Lub receiver muaj ib tug tsis ua hauj lwm feature uas guarantees ib tug logic-siab tso zis yog hais tias lub input qhib Circuit Court.
DS1487 muaj nyob rau hauv cov pob khoom ntog thiab DIP.
