Nqe lus piav qhia:
TCA9548A I2C Multiplexer Module yog txhawm rau txuas cov cuab yeej nrog tib I2C chaw nyob (mus txog 8 qhov chaw nyob tib I2C) txuas rau ib lub microcontroller. Multiplexer ua tus saib xyuas lub qhov rooj, kaw cov lus txib mus rau pawg I2C tus pin xaiv nrog koj cov lus txib. Multiplexer nws tus kheej nyob ntawm I2C chaw nyob 0x70 (tab sis tuaj yeem hloov kho los ntawm 0x70 txog 0x77), tsuas yog sau ib qho byte nrog qhov xav tau ntau tus lej tso tawm mus rau qhov chaw nres nkoj, txhua lub pob I2C yav tom ntej yuav tau xa mus rau qhov chaw nres nkoj ntawd. Hauv kev xav, koj tuaj yeem muaj 8 ntawm cov lej sib txawv no ntawm txhua qhov 0x70-0x77 chaw nyob txhawm rau tswj hwm 64 ntawm tib-I2C-hais-ib feem
Kev qhia tshwj xeeb:
- 8 tawm ntawm 1 txoj kev hloov pauv ob txoj hauv kev nrog
- I2C tsheb npav thiab kev tswj hwm lub npav (SMBus) tau txais kev txhawb nqa qis pib dua
- Peb qhov chaw nyob tus pin ntawm ISupports txog yim ntawm 2C tsheb npav TCA9548A
- Txhawb nqa qhov ntsuas hluav taws xob nruab nrab ntawm 1.8V, 2.5V, 3.3V thiab 5V kev hloov tsheb npav
- Kev siv hluav taws xob ntau qhov hluav taws xob ntau yog 1.65V txog 5.5V5V qhov hluav taws xob nkag
- 0 txog 400kHz moos zaus
- Loj: 30mm x 20mm
- Xim: ntshav
