TXS0104VRUTR in TXS0108 / BSS138 Level Shifters Family
The TXS0104VRUTR, part of the TXS0108 and BSS138 level shifter family by Texas Instruments, is a four-bit bidirectional voltage-level translator designed for applications where open-drain or push-pull signaling is required. Unlike traditional buffers, it utilizes an auto-direction sensing architecture that eliminates the need for a direction control pin. Supporting a wide voltage range from 1.65V to 5.5V, it serves as a critical bridge between legacy components and modern low-voltage microcontrollers and processors.
Variants within the TXS series differ primarily in bit count, ranging from single-bit (TXS0101) to eight-bit (TXS0108) configurations. Package options vary significantly, including space-saving UQFN (VRUTR) and VSSOP packages to meet different thermal and assembly requirements. While the core auto-sensing architecture remains consistent, specific variants may offer different integrated pull-up resistor values or extended temperature ratings for automotive and aerospace applications.
