Kusanthula IC 7400: Kusankhidwa, kusinthidwa kwa pini, ndi mapulogalamu othandiza
2024-09-09 4541

IC 7400 ndi chinthu choyambira mu zamagetsi zamagetsi, zomwe zimadziwika chifukwa chosinthasintha komanso kuchita bwino kwambiri pakuthana ndi ntchito zosiyanasiyana.Monga gawo la mndandanda wa 7400, IC ili ndi zipata zinayi zokha, zomwe zimapangitsa kuti zikhale nyumba yabwino kwambiri m'magulu onse osavuta komanso ovuta.Kuchokera pamadera oyambira otsogola kuti zisapangidwe ngati Alusi ndi mabasi amabasi, ic 7400 idapangidwa kuti ithandizire mapulogalamu osiyanasiyana.Kusintha kwake, kuphatikiza ndi kuphatikizidwa kwake ndi kuphatikiza kwake, kumapangitsa kuti ikhale chida chamtengo wapatali kwa opanga ndi ochita masewera olimbitsa thupi chimodzimodzi.Kaya limagwiritsidwa ntchito m'mabuku kapena mapangidwe aluso, iC 7400 imapereka njira yothandiza, yodalirika yothetsera ntchito zenizeni.

Kataloji

Chithunzi 1: IC 7400

Kodi IC 7400 ndi chiyani?

The IC 7400 ndi gawo logikika losiyanasiyana la digito lomwe limagwiritsidwa ntchito pamagetsi osiyanasiyana.Kusintha kwake kumapangitsa kuti zikhale zothandiza pazida zochokera ku zigawo zochokera ku zigawo zina zokhudzana ndi mayunitsi a arithmetic (Alus) ndi mabasi.Monga gawo la mndandanda wa 7400, Ichi ikaziyikidwira kuti ikhale ngati malo omanga nyumba.Imathandizira ntchito ngati zipata zoyambira (ndi, kapena, nnd, kapena), kukumbukira kwa ma reirle, komanso ma module a ntchito monga kusintha kwamitundu monga kusinthira.IC 7400 imayamikiridwa kwambiri pa zipata zake zodziyimira pawokhaChipata chilichonse chimakhala ndi zikhomo ziwiri ndi pini imodzi yotulutsa, pomwe zikhomo ziwiri zotsalazo zimapereka mphamvu (vcc) ndi nthaka (Gnd).Malumikizono awa ndi abwino pa ntchito yokhazikika komanso ntchito yodalirika.

Chizindikiro cha IC 7400

Kuzindikira Kusintha kwa zitsulo kwa IC 7400 ndilabwino kuti mukwaniritse zofuna za madera omwe mukufuna.Pini lililonse ili ndi gawo lina lomwe limapangitsa kuti ikhale ntchito yonse ya IC.

Chithunzi 2: IC 7400 PINASTRASTIONG

• Pin 1 (The-kulowetsa pachipata choyamba) - imodzi mwazinthu ziwiri za chipata choyambirira cha nand.Chizindikiro cholumikizidwa apa chiyenera kugwira ntchito ndi pini 2 kuti mudziwe mtundu wa mawu otulutsa pa pini 3.

• Pin 2 (B-kulowetsa pachipata choyamba) - gawo lachiwiri la chipata choyambirira cha nand.Ili ndi pini 1, ndipo zikalowa zonse ndizokwera, zotulutsa (pini 3) zidzakhala zochepa, monga chipata chomveka cha NAnd.

• Pin 3 ..

• Pin 4 (Kulowetsa pachipata chachiwiri)

• Pin 5 .

• Pin 6 .

• Pin 7 .Makina olakwika amatha kubweretsa machitidwe olakwika kapena kulephera kwathunthu kwa ic.

• Pin 8 (Y-zotulutsa pachipata chachitatu) - kutulutsa kwachitatu n

• Pin 9 (B-kulowetsa pachipata chachitatu) - kulowetsa chipata chachitatu, chophatikizidwa ndi pini 10.

• Pin 10 (The-kulowetsa pachipata chachitatu) - amagwira ntchito ndi pini 9 kuti mupange zotulutsa pa pini 8.

• Pin 11 (Y-zotulutsa pachipata chachinayi) - chipata chomaliza chatulutsa, chogwiritsidwa ntchito poyendetsa ntchito zomaliza.

• Pin 13 .

• Pin 14 (Magetsi opatsa) - amapereka mphamvu ya IC.Akatswiri owonetsetsa kuti izi 5V zimangokhala zokhazikika pogwiritsa ntchito ma carporting ang'onoang'ono kuti musule phokoso ndikusunga magetsi osasinthika.

Kulembana

The IC 7400 ili ndi mawonekedwe omwe amapangitsa kuti ikhale chisankho chodalirika kwa mapangidwe a digito ambiri, mphamvu yopanga, liwiro, komanso kulingana ndi mabanja angapo.

• Mphamvu yamagetsi: 5V

Akatswiri amagwiritsa ntchito magetsi olamulira kuti asunge izi mokhazikika, kupewa zolakwika zopangidwa ndi kusintha kwa magetsi.

• Kuchedwa kuchedwa: 10 NS

Nthawi yomwe imatenga siginecha kuti iyende kuchokera ku zoyambitsa kupita.Ngakhale zokwanira kugwiritsa ntchito kwambiri, akaunti ya injiniya yopanga izi mabwalo othamanga kwambiri, pogwiritsa ntchito oscilloscopes kuti mutsimikizire kuti nthawi yonseyi ndi malire.

• Zambiri zapamwamba kwambiri: 25 mhz

Izi zimakhazikitsa malire a zipata zachangu zimatha kusintha pakati pa mayiko.Akatswiri akuyenera kuwonetsetsa kuti kapangidwe kawo kamayendetsa pansi pa nthawi iyi kupewa zolakwa mu mabwalo osintha.

• Kudya kwamphamvu pa chipata: mpaka 10 mw

Kugwiritsa ntchito kwambiri mphamvu kumapangitsa kuti zigawo zisagwiritsidwe ntchito popanda kuzimitsa magetsi.M'machitidwe akuluakulu, mainjiniya amagwiritsa ntchito mphamvu mosamala kuti atsimikizire kuti mwakuthandizani.

• Kuphatikizidwa: Kutsegulira kwa zinthu zinayi

Kupanga kwa IC kumapangitsa mainjiniya kuti apange malingaliro ogikitsira ovuta ndi zochepa chabe.

• Kuphatikizidwa kutanthauzira: TTL, NMO, CMOS

Kugwirizana ndi mabanja osiyanasiyana kumatsimikizira kusinthasintha m'magulu amisikita.Akatswiri ambiri nthawi zambiri amagwiritsa ntchito kupewa kupewa kusinthasintha pakati pa mabanja.

• Kugwiritsa ntchito voliyumu

Ngakhale kuti kufera nthawi zambiri zimakhala pa 5V, imatha kuthana ndi ma volidi osiyanasiyana, ndikulola kuti zisinthe malo osiyanasiyana.

• Zogwiritsa ntchito mosiyanasiyana

ICC imagwira ntchito modalirika m'malo osiyanasiyana.Kutentha kwambiri, mainjiniya kumapangitsa kuti kutentha kumenti kapena makina ozizira kuti asunge magwiridwe antchito.

7400

Miteji ya 7400 imaphatikizapo mitundu yofunika kwambiri ya digito, iliyonse imatumizira maudindo ena mu kapangidwe ka dera.Pansipa pali zodziwika bwino komanso zomwe amakonda:

IC 7400 (Quad 2-Recotion Nand)

Kugwiritsidwa ntchito pazomwe mungagwiritse ntchito, kusinthika kwa signal, ndi ntchito zolondola, 7400 ndi zovuta mu mapangidwe ophweka komanso ovuta.

Ic 7402 (Quad 2-zolowetsa kapena chipata)

Akatswiri amagwiritsa ntchito madera ofunikira omwe amafunikira zotuluka pang'ono pokhapokha zolowetsa zimayambitsa.Ndizabwino kwa mapangidwe owoneka bwino.

IC 7404 (Hex inverter)

Miyezo yazolowera, yangwiro yolumikizirana ndi kusintha kwa nthawi.

IC 7400 n ndi kapangidwe ka pachipata

Chithunzi 3: IC 7400 Kapangidwe ndi Nand

Zipata za IC 7400 za NAMIzi zimapangitsa kuti icho iC-to chida cha maphunziro ndi akatswiri opanga madera.Akatswiri amasudzo nthawi zambiri amazigwiritsa ntchito kuti apange mabwalo ovuta, monga flip-flip-flops kapena masambiridwe, kapangidwe kake kosinthika ndi magawo oyeserera.

Pamsonkhanowu, mainjiniya amaonetsetsa kuti samalani ndi zolakwa.Oscilyoscopes kapena okonda kuwunika amathandizira kutsimikizira kulondola kwa kusintha kwa zizindikiro, makamaka pamapulogalamu othamanga kwambiri.Mu madera okonda kutentha, mainjiniya amagwiritsa ntchito maofesi a mafuta kuti atsimikizire kuti iCally popanda kuwonongeka kwa signal.

Zabwino ndi zovuta

Ubwino	Zovuta

Mapulogalamu

Chithunzi 4: IC 7400 mu pulogalamu yamagetsi yamagetsi

A IC 7400 imagwiritsidwa ntchito kwambiri machitidwe osiyanasiyana:

Njira Zachitetezo: Zimathandizanso zowonjezera kuchokera ku zoyenda kapena chitseko kuti muchepetse ma alarm.

Njira Zodziwikiratu: Oneersers Freezer ndi machenjere oyambitsa ngati opunthwa amawoloka.

Kusachedwa Malangizo: Amazindikira kusintha m'magawo owunikira komanso ma alarms oyambitsa, nthawi zambiri mumasuntha.

Makonzedwe: Imawongolera kugawa madzi mu makina othilira okha pokonza dothi lonyowa.

Mu mapulogalamu onsewa, a IC 7400 akutsimikizira zodalirika zodalirika, kupanga zisakhwima zosavuta, zamphamvu.Kuphatikizidwa kwake komanso kusandulika kwa kuphatikiza kumapangitsa kuti isankhe kusankha mafakitale angapo.

Mapeto

IC 7400 ikupitiliza kukhala chinthu chodalirika mu kapangidwe ka digito ya digito chifukwa cha magwiridwe ake, kusinthasintha, komanso kugwiritsa ntchito mtengo.Ngakhale matekinolo atsopano amatha kupatsa liwiro lamphamvu komanso kugwiritsa ntchito mphamvu zochepa mphamvu, ic 7400 imakhalabe njira yofunika kwambiri kwa opanga ndi okonda masewera.Kutha kwake kulimbana ndi ntchito zosiyanasiyana - kuchokera ku makina otetezeka kuthirira-kumawonetsa kusintha kwake.Kugwirizanitsidwa kwa IC 7400 kwa kuphatikizidwa kumapangitsa kuti ikhale mwalawachikulu mu cholembera ndi zojambula zamakono komanso zojambula za digito, ndikuonetsetsa zomwe zikugwiritsidwa ntchito popitilira mafakitale osiyanasiyana omwe amagwiritsidwa ntchito ndi mapulogalamu osiyanasiyana.
