Inkcazelo ye-TCA9555
Le 16-bit I/O isandisi kwibhasi ye-bidirectional yemigca emibini (I2C) yenzelwe i-1.65-V ukuya kwi-5.5-V VCCoperation.Ibonelela ngokubanzi-injongo ekude yokwandiswa kwe-I/O kuninzi lweentsapho zolawulo oluncinci ngojongano lwe-I2C.
I-TCA9555 iqulathe uLungiselelo lwe-8-bit ezimbini (igalelo okanye ukhetho lwemveliso), isiZibuko soNgeniso, isiZibuko sokuPhuma, kunye nePolarity Inversion (irejista esebenzayo ephezulu okanye esebenzayo ephantsi).Kumandla ombane, ii-I/Os ziqwalaselwe njengamagalelo.Umphathi wenkqubo angenza i-I/Os njengegalelo okanye iziphumo ngokubhalela kwi-I/O bits yoqwalaselo.Idatha yegalelo ngalinye okanye imveliso igcinwa kwirejista yeNgeniso okanye yeZiphumo ehambelanayo.I-polarity yerejista yesiZibuko sokuNgena inokujikwa kunye nerejista yePolarity Inversion.
I-TCA9555 iyafana ne-TCA9535, ngaphandle kokufakwa kwe-internalI / O yokutsala-up resistor, edonsa i-I / O ukuya kwindawo ephezulu xa iqulunqwe njengegalelo kunye ne-undriven.
Izikhonkwane ezintathu ze-hardware (A0, A1, kunye ne-A2) zisetyenziselwa ukucwangcisa idilesi ye-I2C, evumela izixhobo ezisibhozo ze-TCA9555 ukwabelana ngebhasi efanayo ye-I2C okanye i-SMBus.Idilesi ye-I2C emiselweyo ye-TCA9555 iyafana ne-PCF8575, PCF8575C, kunye nePCF8574, ivumela ukuya kuthi ga kwisibhozo sezi zixhobo nakweyiphi na indibaniselwano ukwabelana ngebhasi ye-I2C efanayo okanye i-SMBus.
