Key Features
- 4-bit bidirectional voltage translation between 1.4V–3.6V and 1.65V–5.5V supply rails
- Automatic direction sensing — no direction control pin required
- Supports push-pull and open-drain outputs for maximum flexibility
- Ultra-low propagation delay for high-speed I2C and SPI interfaces
- Tiny SOT-363 (SC-70) package ideal for space-constrained designs
Applications
The TXS0104ED is widely used in mobile devices, wearables, and IoT nodes where mixed-voltage buses connect microcontrollers to sensors, memory, or display modules. It excels in I2C, SPI, and UART level-shifting between 3.3V MCUs and 1.8V or 5V peripherals. Its automatic direction sensing makes it ideal for bidirectional data lines in embedded systems where board space and power consumption are critical.

Frequently Asked Questions
What voltage levels does the TXS0104ED support?
The TXS0104ED supports 1.4V to 3.6V on the VCCA port and 1.65V to 5.5V on the VCCB port. This wide range allows it to translate between common logic levels such as 1.8V, 2.5V, 3.3V, and 5V in the same design.
What interfaces can the TXS0104ED be used with?
The TXS0104ED is compatible with I2C, SPI, UART, and general-purpose GPIO signals. It supports both push-pull and open-drain configurations, making it suitable for a broad range of bidirectional communication interfaces in embedded and consumer electronics.
Does the TXS0104ED require a direction control signal?
No. The TXS0104ED features automatic direction sensing using internal edge-acceleration circuitry. It eliminates the need for an OE or DIR control pin, simplifying PCB routing and firmware design in bidirectional level-shifting applications.
What package does the TXS0104ED come in?
The TXS0104ED is packaged in a 6-pin SOT-363 (SC-70) package, measuring approximately 2mm × 2mm. This compact footprint makes it ideal for portable devices, wearables, and high-density PCB layouts where board real estate is limited.
What is a good replacement or alternative for the TXS0104ED?
Common alternatives include the TXS0104E (TSSOP-14 package), TXB0104 (push-pull only, same voltage range), and NXP PCA9306 for I2C-specific level shifting. The choice depends on interface type, package preference, and whether open-drain support is required.
