TXB0108PWR in TXS0108 / BSS138 Level Shifters Family
The TXB0108PWR is a high-performance, 8-bit bidirectional voltage-level translator from Texas Instruments featuring auto-direction sensing. It facilitates seamless communication between devices operating on different supply rails, spanning from 1.2V to 3.6V on Port A and 1.65V to 5.5V on Port B. By eliminating the need for a direction-control signal, it simplifies PCB routing and reduces GPIO overhead in complex multi-voltage embedded systems. This device is particularly effective for push-pull CMOS logic interfaces.
Variants in This Sub-Family
Variants within the TXB0108 sub-family primarily differ by package type and environmental grading. While the TXB0108PWR signifies the standard TSSOP-20 package, the TXB0108RGYR offers a space-saving QFN package with an exposed thermal pad. Automotive-grade versions, denoted by the -Q1 suffix, provide AEC-Q100 qualification for harsher operating temperatures and reliability standards. Engineers should also note that the TXB series requires specific decoupling and loading considerations compared to the TXS series.
