TXS0104E in TXS0108 / BSS138 Level Shifters Family
The TXS0104E is a 4-bit bidirectional voltage level translator designed by Texas Instruments for interfacing between disparate logic voltage domains. It utilizes a pass-gate architecture with internal pull-up resistors to facilitate open-drain and push-pull communication without a dedicated direction-control pin. It supports voltage levels from 1.65V to 3.6V on Port A and 2.3V to 5.5V on Port B, making it ideal for bridging legacy 5V systems with modern low-voltage microcontrollers.
Variants in This Sub-Family
Variants within the TXS0104 family primarily differ by their packaging and temperature ratings. While the core silicon architecture remains consistent across the series, options include space-saving DSBGA, standard TSSOP, and VQFN packages. Some variants are automotive-qualified (Q100) for high-reliability environments, whereas others are optimized for consumer-grade thermal ranges. Always verify the specific package thermal resistance (Rja) as it impacts maximum frequency performance in high-density layouts.
