Khoom Taw Qhia

SN74CB3Q3245 tau teeb tsa raws li 8-ntsis tsheb npav hloov nrog ib qho kev tso tawm-tsim (OE\) cov tswv yim.Thaum OE qis qis, lub npav hloov tsheb yog ON thiab qhov chaw nres nkoj A txuas nrog B chaw nres nkoj, tso cai rau cov ntaub ntawv bidirectional ntws ntawm cov chaw nres nkoj.Thaum OE siab siab, lub npav hloov tsheb yog OFF thiab lub xeev siab impedance muaj nyob nruab nrab ntawm cov chaw nres nkoj A thiab B.

Cov cuab yeej no tau teev tseg tag nrho rau cov ntawv thov siv hluav taws xob ib nrab siv Ioff.Lub Ioff circuitry tiv thaiv kev puas tsuaj tam sim no rov qab los ntawm lub cuab yeej thaum nws raug kaw.Cov cuab yeej muaj kev sib cais thaum lub hwj chim tawm.

Txhawm rau kom ntseeg tau tias lub xeev siab impedance thaum lub zog nce lossis lub zog poob, OE yuav tsum tau khi rau VCC los ntawm kev rub tawm resistor;qhov tsawg kawg nkaus tus nqi ntawm tus resistor yog txiav txim los ntawm lub tam sim no-sinking peev xwm ntawm tus neeg tsav tsheb.
