TXS0104VRGYR in TXS0108 / BSS138 Level Shifters Family
The TXS0104VRGYR by Texas Instruments is a 4-bit bidirectional voltage level translator designed specifically for interfacing between legacy and low-voltage systems. Unlike traditional buffers, it utilizes an open-drain/pass-gate architecture with internal pull-up resistors, eliminating the need for a direction-control signal. This makes it ideal for mixed-voltage environments requiring seamless communication across VCCA (1.2V to 3.6V) and VCCB (1.65V to 5.5V) rails while maintaining signal integrity at relatively high data rates.
Variants within the TXS sub-family primarily differ by bit count (2, 4, or 8 bits) and package type, such as VQFN, TSSOP, or wafer-level chip scale packaging (DSBGA). While the core translation logic remains consistent, certain variants are optimized with different internal pull-up resistor values or thermal ratings to suit specific industrial or automotive AEC-Q100 standards, ensuring reliability across varying temperature ranges.
