TXB0104QRUTRQ1 in TXS0108 / BSS138 Level Shifters Family
The TXB0104QRUTRQ1 by Texas Instruments is an automotive-qualified (AEC-Q100) 4-bit bidirectional voltage-level translator featuring two independent configurable power-supply rails. It allows for seamless data transfer between 1.2V and 3.6V on the A-port and 1.65V and 5.5V on the B-port without a direction-control signal. Utilizing an auto-direction sensing architecture, it is ideal for bridging mismatched I/O levels between microprocessors and lower-voltage peripherals in modern automotive and industrial systems.
Variants in This Sub-Family
Variants in this family differ primarily by package type, such as UQFN or TSSOP, and automotive qualification status. While the TXB0104-Q1 series is specifically tested for automotive environments, the standard TXB0104 series serves commercial and industrial markets. Additionally, variants like the TXS series incorporate integrated pull-up resistors, making them more suitable for open-drain protocols compared to the push-pull optimized TXB series.
