TXB0104RUTR in TXS0108 / BSS138 Level Shifters Family
The TXB0104RUTR is part of Texas Instruments' TXB series, a family of 4-bit bidirectional voltage-level translators designed for multi-voltage digital systems. These components utilize two independent power rails to enable seamless data transfer between signals ranging from 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port. Unlike traditional level shifters, the TXB family features automatic direction sensing, eliminating the need for a dedicated direction control signal from the host processor.
Variants in This Sub-Family
Variants within the TXB0104 sub-family differ primarily in packaging and temperature ratings. The 'RUTR' suffix denotes a small-form-factor UQFN package (1.7mm x 2.0mm), whereas 'PWR' versions use TSSOP. Some variants are automotive-qualified (Q100), offering extended temperature ranges for harsh environments. Performance characteristics like propagation delay and maximum data rate remain consistent across packages, though thermal dissipation limits vary significantly between QFN and leaded options.
