ISO721, ISO721M, ISO722, thiab ISO722M yog cov kev sib cais digital nrog cov logic input thiab tso zis tsis sib cais los ntawm silicon dioxide (SiO2) rwb thaiv tsev thaiv. Qhov kev thaiv no muab kev sib cais galvanic txog li 4000 VPK ib VDE. Siv ua ke nrog cov khoom siv hluav taws xob sib cais, cov khoom siv no tiv thaiv cov suab nrov nrov ntawm cov ntaub ntawv tsheb npav lossis lwm cov circuits los ntawm kev nkag mus rau hauv av hauv cheeb tsam, thiab cuam tshuam los yog ua rau lub cev muaj zog.

Lub teeb liab binary input yog conditioned, txhais mus rau ib tug balanced teeb liab, ces txawv los ntawm lub capacitive cais barrier. Nyob rau hauv ib qho kev sib cais barrier, tus sib piv sib txawv tau txais cov ntaub ntawv hloov pauv ntawm cov logic, tom qab ntawd teeb tsa lossis rov pib dua lub flip-flop thiab cov khoom tso tawm raws li. Lub sijhawm hloov tshiab mem tes raug xa mus hla qhov thaiv kom ntseeg tau tias qib dc tsim nyog ntawm cov zis.

Yog tias qhov no dc-refresh pulse tsis tau txais ntau dua 4μs, cov tswv yim yog xav tias tsis muaj zog lossis tsis ua haujlwm, thiab tsis muaj kev ruaj ntseg Circuit Court drives cov zis mus rau lub xeev logic-siab.

Lub symmetry ntawm dielectric thiab capacitor nyob rau hauv lub integrated circuitry muab kev sib raug zoo capacitive, thiab tso cai rau ceev ceev transient voltage hloov ntawm lub input thiab tso zis cheeb tsam yam tsis muaj corrupting cov zis. Lub peev xwm me me thiab lub sijhawm ua haujlwm tas li muab rau kev ua haujlwm nrawm nrog cov teeb liab ntawm {{{0}}} Mbps (DC) txog 100 Mbps rau ISO721 thiab ISO722 cov khoom siv, thiab 0 Mbps rau 150 Mbps nrog ISO721M thiab ISO722M cov khoom siv.

Cov khoom siv no xav tau ob qhov hluav taws xob ntawm 3.3 V, 5 V, lossis ib qho kev sib xyaw ua ke. Tag nrho cov inputs yog 5-V kam rau thaum muab los ntawm ib tug 3.3-V mov thiab tag nrho cov outputs yog 4 mA CMOS.

Cov khoom siv ISO722 thiab ISO722M suav nrog cov khoom siv qis-tsawg tso cai rau thaum tsav mus rau qib siab logic, tso cov khoom tso tawm rau hauv lub xeev siab impedance thiab tua hluav taws xob sab hauv hluav taws xob kom txuag hluav taws xob.

Ob lub ISO721 thiab ISO722 cov khoom siv muaj TTL qhov pib pib thiab lub suab nrov ntawm cov tswv yim uas tiv thaiv cov pulses mus txog 2 ns nyob rau lub sijhawm tsis dhau mus rau qhov tso zis ntawm lub cuab yeej.

Cov khoom siv ISO721M thiab ISO722M muaj CMOS VCC / 2 input thresholds, tab sis tsis muaj lub suab nrov- lim thiab ncua kev nthuav tawm ntxiv. Cov yam ntxwv ntawm ISO721M cov cuab yeej no kuj muab rau kev ua haujlwm qis-jitter.

ISO721, ISO721M, ISO722, thiab ISO722M cov cuab yeej yog tus yam ntxwv rau kev ua haujlwm dhau qhov kub ntawm qhov ntsuas kub ntawm -40 degree txog 125 degree.
