TXS0104VPWR in TXS0108 / BSS138 Level Shifters Family
The TXS0104VPWR is a 4-bit bidirectional voltage level translator manufactured by Texas Instruments, designed for interfacing disparate logic levels in multi-voltage systems. Utilizing an open-drain architecture with internal pull-up resistors, it facilitates seamless communication between subsystems operating at different power rails ranging from 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port. It is a staple in embedded design for bridging modern low-voltage microcontrollers with legacy sensors or peripherals.
Variants within this sub-family primarily differ by package type, such as TSSOP (PW), VQFN (RGY), or UQFN (RSV), and temperature ratings. While the core TXS architecture remains consistent, different suffixes denote lead-free finishes or tape-and-reel quantities. Some variants are specifically automotive-qualified (Q1 suffix) to meet AEC-Q100 standards for reliability in harsh environments, though electrical performance across the 1.2V to 5.5V range remains largely uniform.
