TCA9548APWR TSSOP-24 Izingxenye ze-elekthronikhi isekethe ehlanganisiwe I-Logic chip 1.65V-5.5V

Incazelo emfushane:

I-TCA9548APWR 8-channel 1.65- kuya ku-5.5-V I2C/SMBus switch enokusetha kabusha nokuhumusha kwe-voltage

Idivayisi ye-TCA9548A inamaswishi okuhumusha aqondiswa kabili angalawuleka ngebhasi le-I2C.Abalandeli be-SCL/SDA abakhuphuka nomfula baphumela kumapheya ayisishiyagalombili ezansi nomfula, noma iziteshi.Noma isiphi isiteshi se-SCn/SDn noma inhlanganisela yamashaneli ingavalwa, kunqunywa okuqukethwe kurejista yokulawula ehlelekayo.Lezi ziteshi ezingezansi zingasetshenziselwa ukuxazulula izingxabano zekheli lesigqila le-I2C.Isibonelo, uma izinzwa zokushisa zedijithali ezifanayo eziyisishiyagalombili zidingeka kuhlelo lokusebenza, inzwa eyodwa ingaxhunywa esiteshini ngasinye: 0-7.

Umphathi wesistimu angakwazi ukusetha kabusha i-TCA9548A uma kwenzeka ukuphela kwesikhathi noma okunye ukungasebenzi kahle ngokugomela okuphansi kokokufaka kwe-RESET.Ngokufanayo, ukusetha kabusha amandla kuyeka ukukhetha zonke iziteshi futhi kuqalise umshini wombuso we-I2C/SMBus.Ukugomela okuthi RESET kubangela ukusetha kabusha okufanayo kanye nokuqalisa ukuthi kwenzeke ngaphandle kokunciphisa ingxenye.Lokhu kuvumela ukululama uma elinye lamabhasi e-downstreamI2C libhajwa esimeni esiphansi.

Amasango okudlula amaswishi akhiwe ukuze iphinikhodi ye-VCC isetshenziselwe ukukhawulela amandla aphezulu aphezulu, adluliswa yi-TCA9548A.Ukukhawulela amandla kagesi aphezulu kakhulu kuvumela ukusetshenziswa kwama-voltage ebhasi ahlukene kupheya ngayinye, ukuze izingxenye ezingu-1.8-V, 2.5-V noma 3.3-V zikwazi ukuxhumana nezingxenye ezingu-5-V, ngaphandle kwanoma yikuphi ukuvikela okwengeziwe.Izinqamuli zokudonsa zangaphandle zidonsa ibhasi lifike ezingeni likagesi elifiselekayo esiteshini ngasinye.Wonke amaphinikhodi e-I/O ayakwazi ukubekezela okungu-5-V.

Incazelo ye-TCA9548A

Idivayisi ye-TCA9548A inamaswishi ahumushayo ayisishiyagalombili angalawuleka ngokusebenzisa i-I.²C ibhasi.Abalandeli be-SCL/SDA abakhuphuka nomfula baphumela kumapheya ayisishiyagalombili ezansi nomfula, noma iziteshi.Noma isiphi isiteshi se-SCn/SDn noma inhlanganisela yamashaneli ingavalwa, kunqunywa okuqukethwe kurejista yokulawula ehlelekayo.Lezi ziteshi ezingezansi zingasetshenziswa ukuxazulula i-I²Ukungqubuzana kwekheli lesigqila.Isibonelo, uma izinzwa zokushisa zedijithali ezifanayo eziyisishiyagalombili zidingeka kuhlelo lokusebenza, inzwa eyodwa ingaxhunywa esiteshini ngasinye: 0-7.

Umphathi wesistimu angakwazi ukusetha kabusha i-TCA9548A uma kwenzeka ukuphela kwesikhathi noma okunye ukungasebenzi kahle ngokugomela okuphansi kokokufaka kwe-RESET.Ngokufanayo, ukusetha kabusha amandla kuyeka ukukhetha zonke iziteshi futhi kuqalise i-I²Umshini wombuso we-C/SMBus.Ukugomela okuthi RESET kubangela ukusetha kabusha okufanayo kanye nokuqalisa ukuthi kwenzeke ngaphandle kokunciphisa ingxenye.Lokhu kuvumela ukutakula uma enye ye-downstreamI²Amabhasi akwa-C abhajwa esimeni esiphansi.
