TCA9548APWR
Texas InstrumentsTCA9548APWR is an 8-channel I2C/SMBus switch from Texas Instruments in a 24-pin TSSOP package, with reset and voltage translation — for multiplexing one I2C bus to eight downstream buses. Its advantage is address-conflict resolution: sensors with fixed I2C addresses that cannot coexist on one bus each get their own channel, plus voltage translation between 1.65 V and 5.5 V domains. Selection advice: the PWR suffix denotes TSSOP-24 on tape and reel — match the full code to your layout. Confirm your downstream device count against the 8-channel capacity, and note the access rule behind the address-conflict resolution: the control register can enable any combination of channels simultaneously, but enabling channels together does not clear a clash between devices that share one I2C address — they would answer at the same time and collide, so same-address devices must be accessed one channel at a time, isolated per channel.
