Key Features
- Dual fixed-direction level shifting for reliable 1.8 V to 5 V logic translation in mixed-voltage systems
- Enable-high control pin for tri-state output management and bus sharing across multiple devices
- Ultra-compact 8-pin SOT-23 package with 5 pF load capacitance for high-speed signal integrity on space-constrained PCBs
Applications
The TXU0102DCUR is ideal for bridging 1.8 V microcontrollers to 3.3 V or 5 V peripheral devices such as sensors, displays, and memory modules. Its fixed-direction dual-channel architecture simplifies design of SPI and UART interfaces where signal direction is predetermined. The enable-high control makes it suitable for bus arbitration and power management schemes in portable consumer electronics and IoT edge nodes.

Frequently Asked Questions
What logic voltage levels does the TXU0102DCUR support for level translation?
The TXU0102DCUR translates logic levels between 1.8 V and 5 V supply domains, enabling reliable communication between low-voltage microcontrollers and legacy 5 V peripherals. With a 5 pF typical load capacitance rating, it maintains signal integrity at high switching speeds up to tens of megahertz in typical PCB environments.
How does the enable-high control pin work in the TXU0102DCUR for bus management?
The TXU0102DCUR features an active-high enable pin that, when driven low, places all outputs in a high-impedance state, effectively disconnecting the device from the bus. This allows multiple level translators sharing the same signal lines to be selectively activated, which is essential for multi-master I2C or SPI bus designs with 2 or more devices.
Is the TXU0102DCUR suitable as a replacement for the SN74LVC1T45 in dual-channel designs?
The TXU0102DCUR provides 2 fixed-direction channels in a single 8-pin package, whereas the SN74LVC1T45 offers 1 bidirectional channel per package. For applications requiring 2 fixed-direction translations at 1.8 V to 3.3 V or 5 V, the TXU0102DCUR consolidates both channels into one 8-pin SOT-23 footprint, reducing component count by at least 1 IC and saving board space in compact designs.
Which communication interfaces benefit most from integrating the TXU0102DCUR in IoT hardware?
SPI, UART, and single-wire interfaces operating at data rates up to 100 Mbps benefit most, as the TXU0102DCUR handles fixed-direction logic translation without requiring direction-control firmware overhead. Its 5 pF load capacitance and 8-pin package make it compatible with tight PCB layouts typical in IoT sensor nodes running on 1.8 V microcontrollers connected to 3.3 V or 5 V radios and displays.
