TXB0104QWBQARQ1 in TXS0108 / BSS138 Level Shifters Family
The TXB0104QWBQARQ1 family by Texas Instruments consists of automotive-qualified, 4-bit bidirectional voltage level translators. These devices utilize two separate configurable power-supply rails to bridge communication between mismatched voltage domains ranging from 1.2V to 3.6V and 1.65V to 5.5V. Unlike traditional buffers, this family features auto-direction sensing, eliminating the need for a direction-control signal, which simplifies PCB routing and reduces GPIO overhead in complex automotive and industrial embedded systems.
Variants in This Sub-Family
Variants within this automotive sub-family differ mainly in package dimensions, such as the ultra-thin VQFN (RGY) versus the smaller BQFN (RQA) footprints, and their specific temperature ratings. While the core silicon architecture remains consistent across the TXB0104 line, the Q1 suffix denotes rigorous automotive-grade testing, including enhanced ESD protection and stricter manufacturing process controls compared to standard commercial-grade TXB variants.
