TXB0108QPWRQ1 in TXS0108 / BSS138 Level Shifters Family
The TXB0108QPWRQ1 family by Texas Instruments consists of 8-bit bidirectional voltage-level translators designed for bridging mismatched logic domains. These devices utilize a specialized architecture with automatic direction sensing, eliminating the need for a dedicated direction control signal. Primarily engineered for automotive and industrial systems, they facilitate seamless communication between low-voltage microcontrollers and higher-voltage peripherals or sensors while maintaining signal integrity across asynchronous data paths ranging from 1.2V to 5.5V.
Variants in This Sub-Family
Variants within this sub-family primarily differ by automotive qualification (AEC-Q100), packaging options, and operating temperature ranges. While the core TXB0108 architecture remains consistent, the Q1 suffix denotes rigorous automotive testing and specific assembly site certifications. Other variants may offer different lead pitches or package thermal profiles, such as TSSOP versus VQFN, to suit diverse mechanical constraints in high-density board layouts.
