ISO 1541 DR

ISO1541DR yog ib qho kev sib cais zoo heev IC uas muaj kev ruaj ntseg thiab kev ntseeg siab rau kev sib txuas lus bidirectional I2C. Nws txhawb kev khiav hauj lwm zaus mus txog 1MHz, yog haum rau ib tug dav lub hwj chim mov ntau yam (3V txog 5.5V), thiab muaj ib tug qhib-drain output nrog muaj zog dab dej tam sim no muaj peev xwm.

Kev tsis

ISO1541DR IC tuaj yeem ua haujlwm ib txwm nyob rau hauv ib puag ncig hnyav, muaj kev ua haujlwm kub ntawm -40 degree rau +125 degree, thiab muaj kev tiv thaiv zoo heev. Tsis tas li ntawd, ISO1541DR tau dhau ntau daim ntawv pov thawj kev nyab xeeb, suav nrog cov ntawv pov thawj kev cais tawm, kev tiv thaiv ESD thiab daim ntawv pov thawj rwb thaiv tsev yooj yim, ua kom muaj kev ua tau zoo hauv ntau daim ntawv thov thiab ua kom muaj kev nyab xeeb thiab txhim khu kev qha cov ntaub ntawv xa mus. Txawm hais tias nyob rau hauv kev tswj hwm kev lag luam, cov khoom siv sib txuas lus lossis lwm yam kev lag luam, ISO1541DR yog kev daws teeb meem.

Nqe lus piav qhia:

Cov khoom siv ISO1540 thiab ISO1541 yog cov khoom siv hluav taws xob tsawg, ob txoj kev sib cais uas sib haum nrog kuv²C interfaces. Cov khoom siv no muaj cov tswv yim tawm tswv yim thiab cov khoom tso tawm uas sib cais los ntawm Texas Instruments Capacitive Isolation technology siv silicon dioxide (SiO₂) qhov barrier. Thaum siv cov khoom siv hluav taws xob sib cais, cov cuab yeej no thaiv cov hluav taws xob siab, cais thaj chaw, thiab tiv thaiv cov suab nrov tam sim no nkag mus rau hauv av hauv cheeb tsam thiab cuam tshuam los yog ua rau lub cev muaj zog.

Qhov kev sib cais tshuab no muab kev ua haujlwm, kev ua haujlwm, qhov loj me, thiab kev siv hluav taws xob zoo thaum piv rau optocouplers. Cov khoom siv ISO1540 thiab ISO1541 pab kom muaj kev sib cais ua tiav I²C interface yuav tsum tau ua nyob rau hauv ib tug me me daim ntawv yam.

Lub ISO1540 muaj ob txoj kev sib cais ntawm ob txoj kab rau lub moos thiab cov ntaub ntawv kab thaum ISO1541 muaj cov ntaub ntawv bidirectional thiab lub moos unidirectional. ISO1541 muaj txiaj ntsig zoo hauv cov ntawv thov uas muaj ib tus maub los thaum ISO1540 yog qhov tsim nyog rau ntau daim ntawv thov. Rau cov ntawv thov uas lub moos ncab los ntawm lub hom phiaj yog ua tau, cov cuab yeej ISO1540 yuav tsum tau siv.

Kev sib txuas lus bidirectional yog ua tiav nyob rau hauv cov cuab yeej no los ntawm offsetting lub low-level output voltage ntawm sab 1 mus rau ib tug nqi siab tshaj qhov siab input voltage nyob rau sab 1, yog li tiv thaiv ib tug internal logic latch uas txwv tsis pub yuav tshwm sim nrog standard digital isolators.
