Key Features
- 4-channel unidirectional translation enables high-speed interfacing between 3.3 V and 1.8 V logic domains with 8 ns max delay
- Schmitt trigger inputs provide hysteresis for clean signal translation even with slow-edge or noisy source signals
- Three-state outputs allow bus sharing and isolation when multiple devices must share a common signal line
- 12-pin WQFN package with RoHS-compliant e4 finish suits high-density PCB designs in portable and IoT applications
Applications
The TXU0104RUTR is designed for voltage translation between 3.3 V and 1.8 V (or other low-voltage) logic domains in microcontroller-to-sensor interfaces, SPI and I2C bus level shifting, and UART line adaptation in mixed-voltage system boards. The Schmitt trigger inputs ensure clean digital transitions even when driving capacitively loaded buses with slow signal edges, making it reliable in camera module interfaces and LCD controller connections. Its 4-channel unidirectional architecture also suits GPIO expansion applications in IoT edge nodes, industrial controllers, and consumer electronics where multiple control lines cross voltage domain boundaries.

Frequently Asked Questions
What is the maximum propagation delay of the TXU0104RUTR, and does it support high-speed SPI at 10 MHz?
The TXU0104RUTR guarantees a maximum propagation delay of 8 ns, which is well within the timing budget for SPI interfaces up to 10 MHz where one clock period is 100 ns. Even at 50 MHz SPI, the 8 ns delay represents only 40% of a single 20 ns clock period, leaving adequate setup and hold margin on standard logic families. The Schmitt trigger inputs add a few nanoseconds of hysteresis delay on slow edges, but this remains negligible for signals with rise times faster than 20 ns.
How does the Schmitt trigger input of the TXU0104RUTR improve reliability in capacitively loaded bus applications?
In applications where the bus capacitance exceeds 50 pF — common on long PCB traces or when multiple devices share a 4-wire SPI or I2C bus — the signal rise time slows and can cause multiple toggling without input hysteresis. The TXU0104RUTR's Schmitt trigger inputs reject input oscillations by requiring the signal to cross a lower threshold to switch LOW and an upper threshold to switch HIGH, typically separated by 200–400 mV, ensuring a single clean output transition per input edge even on heavily loaded lines.
Can the TXU0104RUTR translate from a 3.3 V MCU to a 1.8 V sensor, and what supply voltages are required on each side?
Yes, the TXU0104RUTR supports unidirectional translation from a 3.3 V logic driver to a 1.8 V logic receiver. The input side VCCA supply is connected to the source voltage (3.3 V) and the output side VCCB supply to the target voltage (1.8 V), with the device automatically translating the high-level input threshold to the correct 1.8 V output swing. The 4 translated output channels with 3-state capability allow the translator to be disabled when the downstream 1.8 V peripheral is in reset, preventing bus contention.
For a high-volume IoT product, what production availability and environmental compliance does the TXU0104RUTR offer?
The TXU0104RUTR carries a YTEOL indicator of 15 years from Texas Instruments, ensuring long-term production availability suitable for IoT products with multi-year lifecycle requirements. The Pb-free code and JESD-609 e4 finish confirm full RoHS compliance for European and global markets. It is packaged on tape-and-reel (RUTR suffix) in the 12-pin WQFN format, which is compatible with standard 0402-pitch pick-and-place assembly and supports reflow soldering per IPC-7711 guidelines.
