Umdwebo 1: IC 7400

Yini i-IC 7400?

I-IC 7400 iyingxenye ehlukahlukene yedijithali esetshenziswa ezinhlosweni eziningi ze-elekthronikhi.Ukuzivumelanisa nezimo zayo kwenza kube wusizo kumadivayisi asuka kwimibuthako yokuqonda eyisisekelo ezingxenyeni eziyinkimbinkimbi ezifana nama-arithmetic logic Units (alos) nebhasi.Njengengxenye yochungechunge lwe-7400, le ec yakhelwe ukusebenza njengebhulokhi yokwakha imisebenzi yedijithali.Ixhasa imisebenzi efana namasango ayisisekelo anengqondo (futhi, noma, noma i-NAND, noma), ukugcinwa kwedatha namamojula wememori (ye-RAM), kanye nokuhumusha amayunithi wemisebenzi njengokuguqula kanambambili okufana ne-decimal.I-IC 7400 ibekelwe ikakhulukazi amasango ayo amane afudumele ama-NAnd ama-NAnd, asetshenziswa kuyo yomibili imiklamo ye-logic ehlanganisiwe futhi elandelanayo.Isango ngalinye linezikhonkwane ezimbili zokufaka kanye ne-PIN eyodwa yokukhipha, ngenkathi izikhonkwane ezimbili ezisele zihlinzeka ngamandla (VCC) nangomhlabathi (GND).Lokhu kuxhumana kulungele ukusebenza okuzinzile nokusebenza okuthembekile.

IC 7400 PIN CUMINCURATION

Ukuqonda ukucushwa kwe-PIN ye-IC 7400 kulungele ukufeza indlela yokuziphatha efundela oyifunayo.I-PIN ngayinye inendima ethile ethonya umsebenzi we-IC wonke ohlelweni.

Umdwebo 2: IC 7400 PIN PIN

• Pin 1 (Okufakwayo kwesango lokuqala) - okukodwa kokufakwa okubili kwesango lokuqala leNand.Isiginali exhunywe lapha kufanele isebenze nge-PIN 2 ukuthola isimo sokuphuma se-Pin 3.

• PIN 2 (B-Okokufaka kwesango lokuqala) - okokufaka kwesibili kwesango lokuqala leNand.Amabili ngababili nge-PIN 1, futhi lapho bobabili okokufaka kuphezulu, okukhishwayo (iPIN 3) kuzoba okuphansi, njengokuthi nge-NAMP Gate Logic.

• Phina 3 (Y-Output yesango lokuqala) - Ukukhishwa kwesango lokuqala leNand, ukuhlinzeka ngomphumela we-inverted of the nokusebenza phakathi kwezikhonkwane 1 no-2.

• PIN 4 (Okufakwayo kwesango lesibili) - okufanayo nePin 1 kodwa ngesango lesibili leNand, le phini ithola okokufaka emiklamo eyinkimbinkimbi.

• PIN 5 (B-Okokufaka kwesango lesibili) - ngababili ngePin 4 ukulawula okukhipha kuPin 6.

• PIN 6 (Y-Output yesango lesibili) - Ukukhishwa kwesibili kwesango le-NAT NAT, esetshenziswa ekwakheni amasekethe ama-logic abumbana noma alawule izigaba zakamuva ekwakhiweni.

• PIN 7 .Isisekelo esingalungile singaphumela ekuziphatheni okungalungile noma ukwehluleka okuphelele kwe-IC.

• PIN 8 (Y-Output yesango lesithathu) - Ukukhishwa kwesango lesithathu leNand, kubhekwe ngesikhathi sokudilizwa ukuze kuqinisekiswe ukusebenza okulungile.

• PIN 9 (B-Okokufaka kwesango lesithathu) - Okokufaka kwesango lesithathu, kubhangqwe nge-PIN 10.

• PIN 10 (Okufakwayo kwesango lesithathu) - Isebenza ngePin 9 ukukhiqiza okukhipha ku-PIN 8.

• Phina 11 (Y-Output yesango lesine) - Umphumela weSango lokugcina, osetshenziselwa ukushayela imisebenzi yokugcina ye-Final-Stage.

• Phina 12 (B-Okokufaka kwesango lesine) - Okokufaka kwesango lokugcina leNand, kubhangqwe ngePin 13.

• Pin 13 (Okufakwayo kwesango lesine) - Ukufaka lokho, ngokubambisana nePin 12, kunquma isimo sokukhipha ePin 11.

• PIN 14 (Amandla kagesi atholakalayo) - ahlinzeke amandla we-IC.Onjiniyela baqinisekisa ukuthi lokhu kufakwa kwe-5V kuhlala kuzinzile ngokusebenzisa ama-capacitor asoma

Ukucacisa

I-IC 7400 inokucaciswa okwenze kube yisinqumo esithembekile semiklamo eminingi yesifunda yedijithali, amandla okulinganisa, isivinini, kanye nokuhambisana nemindeni eminingi enengqondo.

• Ukusebenza kwamandla kagesi: 5V

Onjiniyela basebenzisa ama-voltage arterators ukugcina lokhu kufakwa kuqinile, ukuvimbela amaphutha anengqondo okubangelwa ukuguquguquka kwamandla kagesi.

• ukubambezeleka kokusakazwa: 10 ns

Isikhathi esithatha isiginali ukuhamba kusuka kokufaka kokukhipha.Ngenkathi wanele ukutholakala okuningi, i-Engineers Akhawunti yalokhu kubambezeleka okusheshayo, kusetshenziswa ama-Oscilloscopes ukuqinisekisa ukuthi sonke isikhathi singaphakathi kwemingcele eyamukelekayo.

• Ubuningi bokuguqula imvamisa: 25 mhz

Lokhu kusetha umkhawulo wejubane lokuthi amasango asheshe angashintsha ngokushesha kangakanani phakathi kwezifundazwe.Onjiniyela kumele baqinisekise ukuthi ukuklanywa kwabo kusebenza ngaphansi kwalemvamisa ukugwema amaphutha emibuthanweni eshintsha ngokushesha.

• Ukusetshenziswa kwamandla ngesango ngakunye: kufika ku-10 mw

Ukusetshenziswa kwamandla okuphansi kuvumela i-ICS amaningi ukuthi isetshenziswe ngaphandle kokulayisha ngokweqile ukunikezwa kwamandla.Ezinhlelweni ezinkulu, onjiniyela benza isabelomali samandla ngokucophelela ukuze kuqinisekiswe ukusebenza kahle.

• Ukwakheka: Amasango ama-NAnd ama-NAnd angu-2 azimele

I-modular design ye-IC ivumela onjiniyela ukwakha izinhlelo eziyinkimbinkimbi ze-logic ngezakhi ezimbalwa eziyisisekelo.

• Ukukhishwa kokukhishwa: I-TTL, NMOS, CMOS

Ukuhambisana nemindeni ehlukahlukene enengqondo kuqinisekisa ukuhlanganiswa okubushelelezi ezinhlakeni zobuchwepheshe ezixubile.Onjiniyela bavame ukusebenzisa abamelana nama-voltages afakwe emthethweni phakathi kwemindeni enengqondo.

• Ukusebenza kwamandla kagesi

Ngenkathi i-IC imvamisa isebenza ku-5V, ingaphatha ama-voltages ahlukene, ukuvumela ukuthi ivumelane nezimo ezahlukahlukene zohlelo.

• Izimo zokusebenza ezisebenzayo

I-IC isebenza ngokuthembekile ezindaweni ezahlukene.Emazingeni okushisa abi ngokweqile, onjiniyela basebenzisa amasinki okushisa noma amasistimu wokupholisa ukuze alondoloze ukusebenza.

7400 umndeni

Uchungechunge lwe-7400 lubandakanya uhla lwama-digital logic ICS, ngalinye lisebenza izindima ezithile ekwakhiweni kwesizubuli.Ngezansi kune-ICS ejwayelekile kanye nezinhlelo zazo ezisebenzayo:

IC 7400 (Isango le-Quad 2-Innand Land)

Isetshenziselwa imisebenzi eyisisekelo ye-logic, i-Signal Inversion, kanye nokulandelana kokunegayelwa, okungu-7400 kuyisisekelo emiklamo elula futhi eyinkimbinkimbi.

IC 7402 (Ukufakwa okungu-Quad 2 noma isango)

Onjiniyela basebenzisa lokhu ngemibuthano edinga okuzenzakalelayo okuzenzakalelayo ngaphandle kokuthi okokufaka kusebenze.Ilungele ukwakheka okubucayi kwamandla.

IC 7404 (i-hex inverter)

Ingena amazinga anengqondo, alungele ukuvumelanisa kanye nokulungiswa kwesikhathi.
