TXS0102 in TXS0108 / BSS138 Level Shifters Family
The TXS0102 family, manufactured by Texas Instruments, consists of 2-bit bidirectional voltage-level translators designed for interfacing devices operating at different supply rails. These devices utilize a pass-gate architecture with internal pull-up resistors, making them specifically optimized for open-drain applications like I2C or SMBus without requiring external components. They support a wide voltage range from 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port, providing high flexibility for modern mixed-voltage digital systems.

Variants within the TXS0102 sub-family primarily differ by their physical packaging and automotive qualification status. Standard industrial versions are available in VSSOP, SOT-23, and ultra-small DSBGA (WCSP) footprints for mobile applications. The TXS0102-Q1 variant is AEC-Q100 qualified for automotive environments, offering identical electrical characteristics but with the rigorous testing and reliability standards required for under-the-hood or in-cabin electronic control units.
