TCA9548APWR in TI TCA9548 I2C Multiplexer Family
The TCA9548APWR is a part of Texas Instruments' TCA9548 family of 8-channel I2C switches featuring bidirectional translation and bus multiplexing. Manufactured by TI, this TSSOP-packaged device is designed for applications where I2C address conflicts occur or where the bus needs to be segmented into several branches. It allows a single controller to communicate with up to eight downstream slave devices by dynamically selecting the active channel through internal control registers.
Variants in This Sub-Family
Variants within this sub-family primarily differ by package type and industrial qualification. While the TCA9548APWR uses a Thin Shrink Small Outline Package (TSSOP), other variants may offer VQFN for space-constrained mobile applications. There are also automotive-qualified 'Q1' versions that meet AEC-Q100 standards for temperature and reliability, whereas the standard 'A' suffix denotes the basic industrial temperature range variant.
