Cov khoom siv hauv tsev neeg ISO7220x thiab ISO7221x yog dualchannel digital cais. Txhawm rau pab txhawb PCB layout, cov channel yog taw qhia tib yam hauv ISO7220x thiab cov lus qhia rov qab hauv ISO7221x. Cov khoom siv no muaj lub logic input thiab output buffer sib cais los ntawm TI's silicon-dioxide (SiO2) cais barrier, muab galvanic cais tawm txog li 4000 VPK ib VDE. Siv ua ke nrog cov khoom siv hluav taws xob cais tawm, cov cuab yeej no thaiv qhov muaj hluav taws xob siab thiab qhov chaw sib cais, nrog rau tiv thaiv cov suab nrov nrov ntawm cov ntaub ntawv tsheb npav lossis lwm cov khoom siv hluav taws xob los ntawm kev nkag mus rau hauv av hauv cheeb tsam thiab cuam tshuam los yog ua rau cov hluav taws xob tsis zoo.

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 txhua 4 μs, cov tswv yim yog xav tias tsis muaj zog lossis tsis ua haujlwm, thiab qhov tsis zoo ntawm Circuit Court drives cov zis mus rau lub xeev siab.

Lub peev xwm me me thiab lub sijhawm ua haujlwm tas li muab kev ua haujlwm nrawm nrog cov teeb liab muaj nyob ntawm 0 Mbps (DC) mus rau 150 Mbps (Tus nqi taw qhia ntawm ib kab yog tus naj npawb ntawm qhov hloov pauv hluav taws xob uas tau ua ib thib ob qhia hauv chav nyob bps ). Cov Aoption, B-option, thiab C-option li muaj TTL input thresholds thiab lub suab nrov lim ntawm cov tswv yim uas tiv thaiv cov pulses ib ntus tsis dhau mus rau qhov tso zis ntawm lub cuab yeej. Cov khoom siv M-xaiv muaj CMOS VCC/2 input thresholds thiab tsis muaj lub suab nrov input lim thiab qhov kev nthuav tawm ntxiv qeeb.

Lub ISO7220x thiab ISO7221x tsev neeg ntawm cov khoom siv yuav tsum muaj ob qhov khoom siv hluav taws xob ntawm 2.8 V (C-Qib), 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 2.8-V los yog 3.3-V mov thiab tag nrho cov outputs yog 4-mA CMOS.

Lub ISO7220x thiab ISO7221x tsev neeg ntawm cov khoom siv yog tus cwj pwm rau kev ua haujlwm dhau qhov kub ntawm qhov nruab nrab ntawm -40 degree rau +125 degree .
