Umzobo 1: IC 7400

Yintoni i-IC 7400?

I-IC 7400 ic 7400 yinxalenye ye-Logital ye-Digital yedijithali esetyenziswe kuluhlu olubanzi lweenkqubo ze-elektroniki.Iinguqulelo zayo zenza ukuba kube luncedo kwizixhobo ezivela kwisekethe esisisiseko seLog kwizinto ezinzima kakhulu ezinjengeeyunithi ze-arithmetic (i-alsus) kunye nebhasi.Njengenxalenye yothotho lwe-7400, le i i iyilelwe ukuba isebenze njengebhloko yesakhiwo kwimisebenzi yedijithali.Ixhasa imisebenzi efana namasango esisiseko esisiseko (kwaye, okanye, i-nand okanye), imemori yokungena nge-RAMS (i-RAM), kunye neeyunithi ze-Ram), kunye nokuguqula i-binary ukuya kwi-binal.I-IC 7400 IC ixabisa ngokukhethekileyo kumasango e-zune ye-Nand ye-UNED PAP, esetyenziswayo kuzo zombini izinto ezihlanganisiweyo ze-Locac.Isango ngalinye linezikhonkwane ezimbini zokufaka kunye nePIN enye yemveliso, ngelixa izikhonkwane ezimbini ezisele zibonelela ngamandla (i-VCC) nomhlaba (GND).Olu nxibelelaniso lulungele ukusebenza ngokuzinzileyo kunye nokusebenza okuthembekileyo.

I-IC 7400 isimo sePIN

Ukuqonda ukuqwalaselwa kwePIN ye-IC 7400 iPIN igqibelele ekufezekiseni indlela yokuziphatha yephaluka enqwenelekayo.IPIN nganye inendima ethile enefuthe lomsebenzi we-ic's yenkqubo.

Umzobo 2: I-IC 7400 Isimo sePIN

• IPIN 1 (Igalelo lesango lokuqala) - elinye legalelo elibini lesango lokuqala le-nand.Umqondiso oqhagamshelwe apha kufuneka usebenze ngePIN 2 ukumisela imeko ye-Logic Logic State kwiPIN 3.

• IPIN 2 (Igalelo lesango lokuqala) - igalelo lesibini ngesango lokuqala le-nand.I-IPINI nganye nge-pin 1, kwaye xa zombini igalelo liphezulu, ukukhutshwa (iPIN 3) iya kuba iphantsi, ngokwe-nand ye-NANDA SOTIC.

• IPIN 3 ..

• IPIN 4 .

I-PIN 5 .

I-PIN 6 .

I-PIN 7 .Umhlaba ongalunganga unokubangela ukuba kungabikho nto yokuziphatha okanye ukusilela ngokupheleleyo kwe-IC.

• I-8 .

I-PIN 9 .

• IPIN 10 (Igalelo lesango lesithathu) -Sebenza ngePIN 9 ukuvelisa iziphumo kwiPIN 8.

I-pin 11 .

• IPIN 12 .

I-pin 13 .

• IPIN 14 (I-Voltage elungileyo yokuBonelela) - ibonelela ngamandla e-Ic.Iinjineli ziyaqinisekisa ukuba le nkqubo ye-5V ihlala izinzile ngokusebenzisa i-decoupling kunye ne-Decoveling kwingxolo kunye nokugcina ukuhanjiswa kwee-voltage ezingaguqukiyo.

Inkcazo

I-IC 7400 icacile ekwenzeni ukhetho oluthembekileyo kuyilo oluninzi lwedijithali, ukulinganisa amandla, isantya, kunye nokuhambelana neentsapho ezininzi zeLog.

• I-Volting Reltage: 5V

Iinjineli zisebenzisa ii-voltageotha ukugcina le nkqubo ifihliwe, ukuthintela iziphoso ze-logtic ezibangelwa kukuguquguquka kwevolthi.

• Ukulibaziseka kokunikezelwa: I-10 NS

Ixesha elithathayo lophawu lokuhamba ukusuka kwigalelo kwiziphumo.Ngelixa uninzi lwezicelo, iinjineli ze-Akhawunti yokulibaziseka kwisekethe ezihamba ngesantya esiphakamileyo, kusetyenziswa i-oscilloskopes ukuqinisekisa ukuba lonke ixesha lingaphakathi kwemida eyamkelekileyo.

• Ubuninzi bokutshintsha i-Prequency: 25 MHZ

Oku kucwangcisa umda wesantya malunga nendlela yokutshintsha ngokukhawuleza ngayo amasango ahamba ngokukhawuleza ngayo.Iinjineli kufuneka ziqinisekise ukuba kuyilo lwazo lusebenza ngezantsi kule ndlela iphindaphindiweyo ukuze baphephe iimpazamo kwisekethe ngokukhawuleza.

• Ukusetyenziswa kwamandla ngesango: ukuya kuthi ga kwi-10 MW

Ukusetyenziswa kwamandla asezantsi kuvumela i-ics ezininzi ukuba isetyenziswe ngaphandle kokulayisha umbane.Kwiinkqubo ezinkulu, iinjineli zenza uhlahlo-lwabiwo mali lwamandla ngononophelo ukuqinisekisa ukusebenza kakuhle.

Ukuqulunqwa: I-5 ye-Nand ye-5

Uyilo olusemongolo lwe-IC luvumela iinjineli ukuba zenze iinkqubo ezintsonkothileyo zezinto ezisisiseko.

• Iziphumo zokuhambelana: I-TTL, NMOS, CMOS

Ukuhambelana neentsapho ezahlukeneyo zeLog kuqinisekisa ukudityaniswa okutyebileyo kwiinkqubo zobugcisa ezixubeneyo.Iinjineli zihlala zisebenzisa abahlali ukuba basebenzise i-mismating ye-mismatrication phakathi kweentsapho ze-log.

• Uluhlu lwevolthi yokusebenza

Ngelixa i-ic iqala kwi-5V, inokujongana neevolthi ezahlukeneyo, ivumela ukuba ikwazi ukuziqhelanisa neemeko ezahlukeneyo zenkqubo.

Iimeko zokusebenza eziguquguqukayo

I-IC isebenza ngokuzimela kwiindawo ezahlukeneyo.Kwiqondo lobushushu eligqithileyo, iinjineli zisebenzisa i-share esitshisayo okanye iinkqubo zokupholisa ukugcina intsebenzo.

I-7400 I-IICS SCS

I-7400 i-7800 ibandakanya uluhlu lwee-ics zegita zedijithali, nganye isebenzela iindima ezithile ngendlela yesekethe.Apha ngezantsi kukho ii-ICs eziqhelekileyo kunye nezicelo zabo ezisebenzayo:

I-IC 7400 (i-quad 2-igalelo lend)

Isetyenziselwa imisebenzi esisiseko ye-Logic, isigebenga esiyisikizi, kunye nokusebenza ngokulandelelana, i-7400 i-7400 yi-stappeple kuzo zombini uyilo nolwenziweyo.

I-IC 7402 (i-quad 2-igalelo okanye isango)

Iinjineli zisebenzisa oku kwiisekethe ezifuna iziphumo eziphantsi ezingagqibekanga ngaphandle kokuba igalelo liyasebenza.Ilungele ubuthathaka obunobuthathaka.

I-IC 7404 (i-hex ingaphakathi)

I-Invertic amanqanaba e-Log, igqibelele ekuqulunqweni kunye nohlengahlengiso lwexesha.

I-IC 7400 ye-IAnd yesantya yoyilo lwesekethe

Umzobo 3: I-IC 7400 uyilo lwesekethe nge-nand tic

I-IC 7400 ye-IC 7400's's's ezine ze-Nand ezizimeleyo ze-Nand I-Nand ibonelela ngokuguquka, zivumela naliphi na isango elisisiseko leLog ukuze sakhiwe.Oku kwenza ukuba i-IC ibe sisixhobo sokuya kwizixhobo zemfundo kunye neengcali zesekethe.Iinjineli zihlala ziyisebenzisa ukwakha iziphaluka ezintsonkothileyo, ezinje ngeflip-flops okanye ii-alxers, uyilo olulula kunye nezigaba zokuvavanya.

Ngexesha lendibano, iinjineli ziqinisekisa ingqibelelo efanelekileyo yokuphepha iimpazamo.I-Oscilloscopes okanye ihlalutyo ye-Logic inceda ekuqinisekiseni ukuchaneka kotshintsho lwesiginali, ngakumbi kwizicelo ezikhawulezayo.Kwindawo ezibuthathaka ngamaqondo obushushu, iinjineli zisebenzisa ulawulo lobushushu ukuqinisekisa ukuba i-IC isebenza ngokuthembekileyo ngaphandle kokupheliswa komqondiso.
