A 74l02 ndi IC IC, PIN, monga momwe chithunzi chojambulira chimakhalira.Imapezeka m'mapaketi osiyanasiyana, kulola kusankha kutengera zofunikira zina.Ntchito ya pini iliyonse ikufotokozedwa pansipa.

Maukadaulo ndi mawonekedwe

Mphamvu yamagetsi ndi magetsi

Chigawo chophatikizidwa, chokhala ndi magetsi pakati pa + 4,75 ndi + 5.25V kuphatikiza malire otetezeka a 7v, amathandizira kugwira ntchito bwino.Imathandizira kutulutsa pachipata chamakono kwa 8Ma pachipata, kugwirizanitsa mosadukiza ndi zotulutsa za TTL kuti zithandizire kugwiritsa ntchito digito.Chipangizochi chikuwonetsa kapangidwe kake kamene kamasinthasintha mphamvu yocheperako, ndikugogomezera njira yopita patsogolo ku mphamvu yakumagetsi pakukonzekera magetsi.

Kukhazikika ndi Management

Wokhoza kutulutsa magetsi apamwamba mpaka 3.5kv, iko kukhala kudalirika ngakhale mutakhala osiyanasiyana, kuphatikiza madera omwe amawoneka kuti amatulutsa.Pofika nthawi ndikugwa ma 15ns, imalonjeza kukondera kumbuyo kwa masitepe ogwiritsira ntchito madera a masiku ano.Monga momwe adakumana nazo pazogwiritsa ntchito, izi zidasinthiratu osati kuthamanga komanso kuphatikiza ndi madongosolo osokoneza bongo omwe nthawi ya nthawi imakhala yamtengo.

Kutentha ndi kusungira magalati

Kugwiritsa ntchito bwino pamavuto kuchokera ku 0 ° C mpaka 70 ° C, Active magwiridwe antchito ambiri.Ndikuletsa kusungirako, kupirira -65 ° C mpaka 150 ° C, kupindula ndi zochitika zomwe zimayang'anizana ndi nyengo zovuta panthawi yoyenda ndi malo osungira.Kukhazikika kwake m'mikhalidwe yosiyanasiyana sikugwirizana ndi zokumana nazo pazinthu zamagetsi.

74sls02 kapena chipata

Kulumikizana kwamkati kwa zinayi kapena zigawani mkati mwa chip kumawonetsedwa pansipa.

Chipata chilichonse kapena chipata chilichonse chimachita kapena kugwira ntchito pazinthu ziwiri zothandiza.A kapena chipata chimaphatikiza magwiridwe antchito a chipata kapena pachipata chotsatiridwa ndi chipata, chofotokozedwa monga:

Kapena = kapena + ayi

Tebulo loona la ur kapena chipata ndi motere:

Ikani 1	Inlow2	Kapena zotulutsa	Kapena zotulutsa
Pansi	Pansi	Pansi	M'mwamba
M'mwamba	Pansi	M'mwamba	Pansi
Pansi	M'mwamba	M'mwamba	Pansi
M'mwamba	M'mwamba	M'mwamba	Pansi

Kuti muwonetsetse tebulo loona pamwambapa, losavuta kapena chipata cholumikizidwa monga chikuwonekera pa chithunzi chomwe chili pansipa.

M'derali, omasulira awiri amakonzedwa kuti apange chipata.Zolowa ziwirizi zimalumikizidwa ndi zoyambira za omasulira, ndi mabatani omwe amagwiritsa ntchito mfundo zothandizira.Zotsatira zake zimatengedwa kuchokera kwa osonkhana a ma transtor onse ndikulumikizidwa ndi kutsogozedwa kudzera pakulephera kwaposachedwa.Wotsogozedwayo akuwonetsa mkhalidwe wa zotulutsa, pomwe mabatani amalola kulozera mfundo zolowetsa.

Kapena chipata

• Mabatani onsewo sakanikizidwa

Mu boma lino, palibe zomwe zimayenda kudzera pamitundu ya otumiza Q1 ndi Q2, kusunga ma transtors onse.Zotsatira zake, magetsi athunthu V_Cc limapezeka pa transtors onse awiri.Chiyambire Y₁ Imafanana ndi voliyumu kudutsa Q1 kapena Q2, idzakhala yokwera.Chifukwa chake, mukaloledwa = otsika, kutulutsa = kukwera.

• Ngati batani limodzi limakanikizidwa

Kanikizani batani limodzi limatembenuza tchuthi cholingana pomwe enawo adatsika.The tratsistor imachita ngati bwalo lalifupi, ndikuwongolera transistar.Izi zimabweretsa zero magetsi am'madzi onse omasulira, ndikupanga Y₁ Otsika.Chifukwa chake, mukalowetsa kamodzi = kukwera, kutulutsa = chotsika.

• Mabatani onse akapanikizika

Ndi mabatani onse awiri opanikizika, onse omasulira alipo, ndipo magetsi amenewo ndi zero.Zotsatira zake, Y₁ ndi yotsika.Chifukwa chake, pomwe zoyika zonse ziwiri = zapamwamba, zotuluka = ​​zotsika

Mwa kutsimikizira izi zitatuzi, zikuonekeratu kuti derali limakwaniritsa tebulo loona la a kapena chipata.Kutulutsa mawu akuti kapena chipata ndi:

Chipata chilichonse m'chip chingagwiritsidwe ntchito mofananamo, kutengera zofunikira zina.

Ntchito za 74l02

Kukonzekera kosiyanasiyana kapena mfundo

IC 74l02 iC ndi gawo lopanga kapena logic zipata, kukhala ngati maziko a zotsatira zoyipa.Kusintha kwake kumathandizira kuphatikiza madera osiyanasiyana a digito, kupereka njira zabwino zothandizira mfundo zomveka bwino.Kwa zaka zambiri, tazindikira kuti aics awa amatha kukonza malo ndikuchepetsa kugwiritsa ntchito mphamvu, kusintha kwa kukula kwa chitukuko.Kuphatikiza paubwino waukadaulo, malingaliro a kuzindikira ndi luso la kuzindikira ndi luso lathu akamazimitsa zinthuzi zikuwonetsa kuti ndalamazo zimawonetsera njira zoyenera.

Udindo Wogwiritsa Ntchito Magetsi

Mu zamagetsi zamagetsi, IC yamvula ya 7442 yatsimikizira zofunika.Akaphatikizidwa ndi malingaliro ena ogic, amapangika fupa la mitsinje yama digito.Izi synergy mu injini ya digito imawonetsa momwe ziliri zodalirika zimapangitsa kukhazikika komanso kudalirika, kumathandizira dontho lolephera pamagetsi ogulitsa.Zosangalatsa zomwe zachitika pofuna kukwaniritsa zizindikilo zawo zodalirika, zomwe zimapangitsa kuti kukhazikika kwamasewera azichita zinthu zoyeserera.

Kukulitsa mayunitsi a lirithmetic (Alusi)

Kuphatikiza kwa 74l02 ics mkati mwa mayunitsi a Arithmetic (Alusi) amawonetsa zofunikira zawo pakukwaniritsa ntchito.Monga Assoli wapakati pa mapulogalamu, pofotokoza maofesi a masamu omwe amapereka mapulogalamu omwe amapereka mapulogalamu, kusinthidwa ndi kuphatikiza kwa zinthuzi pokonzanso kuthamanga kwinaku mukukhala kulondola.Izi zimalimbikitsa kunyada pakati pathu omwe amachitira umboni zawo kukakamiza malire a kugwiritsa ntchito magwiridwe antchito, kuphatikiza ukadaulo waukadaulo wam'maganizo.

Seva yabwino ndi kukonza deta

Mu seva ya seva, 74l02 imathandizira kukonza mabwalo omwe amawongolera bwino zotuluka.Mphamvu zake kapena zomveka zili m'malo osungiramo zinthu zomwe zikufanana ndi kuphatikizika kwa data komanso kulimba mtima kwa data kumafunikira.Zochitika za akatswiri zimawunikira momwe zinthuzi sizikuthandizira ntchito zomwe zili zopanda pake komanso zosasinthika, kukwaniritsa zomwe zimapangitsa kuti zikhale zolimba.Kuyankhidwa kwam'maganizo kukwaniritsa zizindikiritso zolimbitsa thupi kumawonekera molimba mtima, kumayendetsa chidwi chopitilira m'munda.

Kupita kwa Maumary 'magwiridwe antchito

Magawo okumbukira amapindulitsa kwambiri chifukwa chophatikizira 74lg02 ictch02 Inde kuti ayang'anire kuwerenga ndi kulemba.Zipata zamitsempha zomwe zimayendetsa zigawozi zimatsogolera zovuta zosungirako za deta zokhala ndi khama lochepa.Mwa kukongoletsa bwino zipata izi, titha kukulitsa moyo wautali ndi kufotokozera kwa ma module okumbukira, kugwirizanitsa ndi kupita patsogolo kwamakono muukadaulo wokumbukira.Pamodzi mwaukadaulo, zomwe zinakhutira nazo zomwe zimathandizira kukumbukira kuthekera ndi kutchulidwa kwaukadaulo ndikugulitsa kwanu paulendo waukadaulo.

Kulimbitsa Mau Networking ndi Ma digito

Udindo wa 74l02 IC mu malo a ma netchking amafikira ku Packet Paketi ndi Kuyenda.Ma protocolocol amadalira ma icle awa kuti akhazikitse mawonekedwe aintaneti.Kukhazikitsa kutsimikizira kuti kuphatikiza izi zophatikizana ndi ma netiweki ndi magwiridwe antchito, chifukwa chowonjezera.Izi zimayambitsa kutsimikiza mtima komanso kukhutitsidwa kwa ife pamene athetsa mavuto osokoneza bongo olankhulana.
