Overview
The TXU0304RUTR is a 4-bit, dual-supply noninverting fixed direction voltage level translator from Texas Instruments. It operates within a VCCA range of 1.08 V to 5.5 V and supports data rates up to 200 Mb/s. The device features low quiescent current of 2.5 uA and a propagation delay of 96 ns. It is housed in a 12-pin UQFN package (1.7x2 mm) suitable for surface mount applications. The operating temperature range spans from -40°C to +125°C.
Feature Summary
- Supports bidirectional data translation between different logic voltage domains
- Features tri-state outputs for bus holding capabilities
- Designed for high-speed communication interfaces such as UART, SPI, and JTAG
Applications
- Interfacing microcontrollers with peripheral devices operating at different voltage levels
- Level shifting for SPI and I2C communication buses
- JTAG interface translation in embedded systems
Procurement Notes
Verify the specific suffix 'RUTR' corresponds to the tape and reel packaging configuration required for your assembly line. Confirm that the 12-UQFN footprint matches your PCB layout guidelines. Ensure the voltage domain requirements align with the 1.08 V to 5.5 V operational range specified in the official datasheet before finalizing procurement.
Selection Notes
Select this component when unidirectional level translation is sufficient for the application design. It is appropriate for systems requiring fixed direction signal flow between 1.8 V, 2.5 V, 3.3 V, and 5 V logic families. Consider alternative models if bidirectional auto-direction sensing or lower propagation delays are strictly required by the system timing constraints.
Part Context
This part belongs to the TXU0304 family of voltage level translators manufactured by Texas Instruments. It is categorized under Logic ICs and specifically designed for translating signals between CMOS logic levels. The device is part of a broader portfolio of level shifters intended for portable and industrial electronics requiring reliable inter-domain communication.
Replacement Considerations
The TXB0304RUTR serves as a functional substitute but offers bidirectional auto-direction sensing rather than fixed direction translation. Designers must verify that the fixed direction architecture of the TXU0304RUTR meets the specific signal flow requirements of the target circuit before swapping components.
