TXB0104RGYR in TXS0108 / BSS138 Level Shifters Family
The TXB0104RGYR belongs to the Texas Instruments TXB family of 4-bit bidirectional voltage-level translators. Designed for bridge-mode interfacing between different voltage domains, it utilizes two independent power rails to enable seamless logic level shifting from 1.2V up to 3.6V. Unlike traditional buffers, the TXB architecture features auto-direction sensing, eliminating the need for a dedicated direction-control signal and making it ideal for push-pull CMOS logic applications where PCB space and pin count are at a premium.
Variants in This Sub-Family
Variants within this sub-family primarily differ based on package footprint, channel count, and temperature rating. While the TXB0104RGYR utilizes a QFN package for space-constrained designs, other variants like the TXB0104PW utilize TSSOP for easier prototyping. Higher channel-count versions like the TXB0108 are available for wider data buses, though they share the same fundamental auto-sensing architecture and voltage range specifications as the 4-bit models.
