TXS0104VQBQARQ1 in TXS0108 / BSS138 Level Shifters Family
The TXS0104VQBQARQ1 is a high-performance, 4-bit bidirectional voltage-level translator manufactured by Texas Instruments, specifically engineered for automotive applications. Part of the TXS family, it enables seamless communication between devices operating on different supply rails ranging from 1.65V to 5.5V. Unlike traditional level shifters, it utilizes an auto-direction sensing architecture that eliminates the need for a direction-control signal, making it ideal for interfacing modern low-voltage microcontrollers with legacy peripherals or sensors in complex mixed-signal environments.
Variants within this sub-family primarily differ based on their automotive qualification levels, packaging options, and thermal ratings. While the core translation logic remains consistent, certain versions offer ultra-compact leadless QFN packages for space-constrained designs, while others utilize standard TSSOP footprints for easier prototyping. Some variants are optimized specifically for low-capacitance loads to maximize data throughput, whereas the Q1 suffix denotes rigorous automotive-grade testing and ESD protection levels.
