TXS0104VBQAR in TXS0108 / BSS138 Level Shifters Family
The TXS0104VBQAR family, manufactured by Texas Instruments, consists of four-bit bidirectional voltage-level translators designed for interfacing digital signals in multi-voltage systems. These devices utilize a pass-gate architecture with integrated pull-up resistors, making them ideal for open-drain protocols like I2C as well as push-pull applications. They facilitate seamless communication between low-voltage processors and high-voltage peripherals, supporting a wide range of operational voltages from 1.2V to 3.6V on the low side and up to 5.5V on the high side.
Variants within this sub-family primarily differ based on their packaging options, such as TSSOP, VQFN, or UQFN, and their specific temperature ratings. While the core translation logic remains consistent, some variants may feature different pull-up resistor values or pinouts optimized for specific high-speed or automotive-grade applications. Engineers should verify the specific package suffix to ensure thermal performance and assembly compatibility meet system requirements.
