I I-74ls02 yi-IC i-IC i-IC, njengoko kubonisiwe kumzobo wePineut.Ifumaneka kwiiphakheji ezahlukeneyo, zivumela ukhetho ngokusekwe kwiimfuno ezithile.Umsebenzi wePIN nganye ichazwe ngezantsi.

Inkcazo yobugcisa kunye neempawu

Ukusebenza kwe-voltage kunye namandla amandla

Isekethe esihlanganisiweyo, kunye nolwalutya lokuhambisa phakathi +4.75 kunye ne + 5.25v kunye nomda ophezulu we-7V, eqinisekisa ukusebenza ngokufanelekileyo.Ixhasa ukukhutshwa kwe-Peak okwangoku kwe-8MA ngesango, ukulungelelanisa ngaphandle kwe-sexl ye-TTL ye-TTL yokuxhasa usetyenziso lweerejithali.Esi sixhobo sibonisa uyilo olunokucinga ngokusetyenziswa kwamandla amancinci, ukugxininisa indlela yokucinga kwangaphambili ukuya kulondolozo lwamandla kuphuhliso lwe-elektroniki.

Ukuqina kunye nolawulo lobushushu

Ukwazi ukugxothwa kwe-elektrostatic kwi-3.5KV, le ic ibonakalisa ukuthembeka nangaphantsi kweemeko ezahlukeneyo, kubandakanya iimeko ezazinyukele.Ngokunyuka nokwawileyo kufutshane ne-15ns, ithembisa ukuqhubekisa okukhawulezayo, ukulungiselela imigangatho yentsebenzo eyomeleleyo efunwa yisekethe yanamhlanje.Njengoko amava kwizicelo, le nto yokulungisa ngokukhawuleza ayikho kuphela ngesantya kuphela kodwa ikwadityaniswa neenkqubo ezintsonkothileyo apho ixesha lokuchaneka ixesha.

Iqondo lobushushu kunye neeparamitha zokugcina

Ukusebenza ngokusebenzayo Ngapheli amaqondo obushushu ukusuka kwi-0 ° C ukuya kwi-70 ° C, i-IC is, i-IC i-ic isebenza kwizicelo ezininzi ezisemgangathweni.Kuyasindisa ukugcina, ukunyamezela ukusuka ku -65 ° C ukuya kwi-150 ° C, ukuzuza ezo meko apho izinto zijongana khona ngexesha lokuhamba kunye nezigaba zokugcina.Ukuqina kwayo kwiimeko ezahlukeneyo kuyangqinwa ngamava ngaphakathi kwe-elektroniki kubathengi.

I-74ls02 okanye isango

Unxibelelwano lwangaphakathi lwesine okanye amasango ngaphakathi kweChip zibonakaliswa ngezantsi.

I-chip nganye okanye isango elikweli chip lenza ukuba ifumane igalelo elibini lelogic.ISango lidibanisa ukusebenza kwesango okanye isango elalilandelwa ngesango, elibonakaliswe njengo:

Okanye = okanye + hayi

Itheyibhile yeNyaniso yeNtaba yeNyango yeyo ngolu hlobo:

Igalelo1	Igalelo2	Okanye iziphumo	Okanye iziphumo
Iphantsi	Iphantsi	Iphantsi	Phezulu
Phezulu	Iphantsi	Phezulu	Iphantsi
Iphantsi	Phezulu	Phezulu	Iphantsi
Phezulu	Phezulu	Phezulu	Iphantsi

Ukubonisa itafile yeNyaniso engasentla, isango elilula okanye isango lixhunyiwe njengoko kubonisiwe kumzobo ongezantsi.

Kule sekethe, abahambileyo bobabini baqwalaselwe ukwenza i-car kunye nesango.Ezi zigalelo zibini ziqhagamshelwe kwiziseko zoziso, ngamaqhosha asetyenziselwa ukulawula i-Logic yegalelo.Iziphumo zithathwe kumqokeleli wokwabiwa okwabelwana ngawo bobabini oothutho kwaye baqhagamshelwe kwi-LED nge-LED nge-Reder.I-LED ibonisa imeko yemveliso, ngelixa amaqhosha avumela ukungcungcutheka kwe-Logic yegalelo.

Okanye amazwe aSango

• Xa amaqhosha omabini acinezelwa

Kule meko, akukho uqukuqela ngoku kwiziseko ze-Q1 kunye ne-Q2, ekugcineni bobabini.Ngenxa yoko, i-voltage epheleleyo V_Cc ivela kuzo zombini iindlela.Kuba imveliso Y₁ Ihambelana ne-voltage kwi-Q1 okanye i-Q2, iya kuphakama.Ke, xa i-inteuts = iphantsi, imveliso = ephezulu.

• Xa iqhosha licinezelwe

Ukucinezela iqhosha elinye kuguqula i-fissing ehambelana nayo ngelixa elinye lingabikho.I-windotor isebenza njengesekethe emfutshane, egqitha ngaphezulu kwendawo yokuhlala.Oku kukhokelela kwi-zero voltage kuzo zombini iindlela zokuhamba, ukwenza Y₁ Iphantsi.Ke ngoko, xa igalelo elinye = liphezulu, impembelelo = iphantsi.

• xa amaqhosha omabini acinezelwa

Ngawo omabini amaqhosha acinezelweyo, bobabini oonoecala baqhubeka, kwaye i-voltage yazo yi-zero.Nje ngeziphumo, Y₁ iphantsi.Yiyo loo nto, xa zombini i-ipututs = phezulu, impembelelo = iphantsi

Ngokuqinisekisa la mazwe mathathu, kucacile ukuba isiphaluka sanelisa itafile yenyani yeyam okanye nesango.Ingqungquthela yemveliso yeka okanye isango yile:

Isango ngalinye kwi-chip linokusetyenziswa ngendlela efanayo, kuxhomekeka kwiimfuno ezithile.
