TXS0102DRLR in TXS0108 / BSS138 Level Shifters Family
The TXS0102DRLR is a 2-bit bidirectional voltage-level translator from Texas Instruments designed for bridge-interfacing devices operating at different supply rails. Utilizing an open-drain architecture with integrated pull-up resistors, it is specifically optimized for I2C and SMBus applications. It supports data rates up to 24 Mbps on push-pull CMOS outputs and 2 Mbps on open-drain systems, bridging voltage domains from 1.2V to 3.6V on the A-port and 1.65V to 5.5V on the B-port.
Variants within the TXS sub-family primarily differ by channel count, ranging from 1-bit to 8-bit configurations like the TXS0101 or TXS0108. The 'DRLR' suffix specifically denotes the SOT-563 package, which is favored for space-constrained designs. Other variants may include automotive-grade (Q1) qualifications or different temperature ratings, though the internal pass-transistor logic remains consistent across the TXS series for I2C-friendly operation.
