TXS0104VDR in TXS0108 / BSS138 Level Shifters Family
The TXS0104VDR, manufactured by Texas Instruments, is a four-bit bidirectional voltage-level translator designed specifically for interfacing between legacy 5V devices and modern low-voltage CMOS logic. Utilizing a pass-gate architecture with internal pull-up resistors, it facilitates seamless data transfer between different voltage domains without a direction-control signal. This makes it an essential component for system designers integrating mixed-voltage ICs, such as microcontrollers, sensors, and displays, across I2C, UART, and GPIO interfaces in space-constrained embedded systems.
Variants within this sub-family primarily differ by channel count, package type, and thermal ratings. While the TXS0104 focuses on four channels, the TXS0102 and TXS0108 offer two and eight channels respectively. Packaging options range from the space-saving VQFN (RGY) to the standard TSSOP (PW), affecting assembly methods and heat dissipation. Some automotive-grade variants (Q1 suffix) include extended temperature range support and AEC-Q100 qualification for harsh environment reliability.
