Kev tsis
HI{{0}}PS RS-485 transceiver yog ib qho kev daws teeb meem zoo thiab muaj txiaj ntsig rau kev sib txuas lus hauv kev lag luam, muab cov yam ntxwv xws li kev tswj hwm tus nqi, ua ntej tseem ceeb rau kev ua tau zoo EMI, thiab kev siv hluav taws xob txuas ntxiv. ntau yam (3.0V txog 5.5V). Nrog rau ntau hom receiver ntau hom (-15.0V rau 20.0V rau ib nrab-duplex, ± 24V rau puv duplex), cov cuab yeej ua kom ntseeg tau kev sib txuas lus hauv cov cheeb tsam nyuaj. ESD tiv thaiv, suav nrog ± 16KV HBM rau tsheb npav pins thiab ± 8KV HBM rau logic pins, txhim khu kev ruaj ntseg. Lub transceiver txhawb cov ntaub ntawv siab (20 Mbps txog 100 ft., 12 Mbps txog 1000 ft. siv CAT-5 UTP) thiab suav nrog kev tiv thaiv tam sim no. Ua haujlwm nyob rau hauv qhov ntsuas kub ntev ({22}} degree rau 125 degree ) thiab ua raws li kev lag luam-tus qauv 75176 tus pin-tawm, HI-4853PS yog qhov kev xaiv zoo rau kev siv ntau hom kev lag luam.

GENERAL DESCRIPTION:
Lub HI{{0}}x cov khoom siv yog cov khoom siv ceev nrawm tswj tau TIA-485/TIA-422-B thiab ISO 8482: 1993 ua raws cov transceivers nrog txuas ntxiv receiver ntau hom rau avionic thiab industrial tswj kev siv. Cov khoom siv tuaj yeem ua haujlwm dhau qhov khoom siv txuas ntxiv (3.0V txog 5.5V) thiab kub (-55˚C txog 125˚C) ntau yam. Lub receiver input hom-hom ntau yam ntawm [-15, 20]V thiab ± 24V rau ib nrab thiab tag nrho duplex configurations feem, yog siv tau tshaj tag nrho cov khoom thiab kub specification. Lub HI-4853 muaj ib tug halfduplex configuration, thiab HI{19}} thiab HI{20}} yog full-duplex. Slew tus nqi yog optimized rau cov ntaub ntawv tus nqi qis dua 25Mbps. Cov neeg tsav tsheb slew-rate tswj thiab ua ntej tseem ceeb txo qis cov khoom siv ntau zaus hauv cov teeb liab tso zis hloov pauv thiab tseem them nyiaj rau impedance mismatch. Cov yam ntxwv no muab qhov zoo tshaj plaws EMI thiab kev ua haujlwm siab, qhov tseem ceeb hauv EMI qhov chaw rhiab heev thiab kev ncaj ncees cov ntaub ntawv txuas cov ntawv thov xws li hauv aerospace thiab kev lag luam tswj.
Cov khoom siv xa tawm tsawg kawg yog ± 1.50V (VDD=3.0V), thiab ± 2.45V (VDD= 4.5V) tso zis theem ntawm qhov ntsuas kub ntev ntawm {{8} } degree rau +125 degree rau hauv qhov sib txawv ntawm 54Ω thiab 50pF.
Lub receiver muaj qhov tseeb Fail-Safe ua haujlwm, muab qhov kev lees paub siab ntawm RO thaum lub tsheb npav qhib-circuit, shortcircuit, lossis idle (tawm tab sis tsis tsav). Tus neeg txais qhov phem tshaj qhov tsawg kawg nkaus input kuj yog tsawg kawg yog 90KΩ, txhawb txog 224 nodes.
