TXB0104 in TXS0108 / BSS138 Level Shifters Family
The TXB0104 by Texas Instruments is a 4-bit bidirectional voltage-level translator designed for applications requiring seamless interfacing between different logic voltage levels. Unlike traditional level shifters, it utilizes an auto-direction-sensing architecture that eliminates the need for a direction control pin. It operates across two independent power rails, supporting translation between 1.2V and 3.6V on Port A and 1.65V and 5.5V on Port B, making it ideal for mixed-voltage digital systems.
Variants in This Sub-Family
Variants within the TXB0104 sub-family primarily differ by their physical packaging and temperature ratings. Package options include the small-footprint UQFN (RGY), TSSOP (PW), and VSSOP (DCU) formats to accommodate varying assembly requirements and space constraints. Some variants are automotive-qualified (Q100), offering extended temperature ranges and more rigorous reliability testing for automotive cockpit and powertrain sensor applications. Electrical characteristics like propagation delay remain consistent across these package variants.
