Product details
Overview
TXU0104RUTR from Texas Instruments is a 4-bit fixed-direction voltage-level translator IC with Schmitt-trigger inputs and 3-state outputs, supporting dual-rail operation from 1.1V to 5.5V per port, up to 200Mbps data rate (3.3V→5.0V), and operating across –40°C to +125°C. It enables robust level shifting in mixed-voltage I/O interfaces such as UART, SPI, and JTAG between microcontrollers and peripherals.
For engineers reviewing the TXU0104RUTR datasheet, TXU0104RUTR pinout, TXU0104RUTR application, or TXU0104RUTR equivalent, this page delivers verified electrical specifications, thermal performance data, OE control behavior, VCC isolation functionality, and real-world use cases for high-noise industrial and automotive embedded systems.
Technical Context
The TXU0104RUTR implements noninverting fixed-direction translation with independent A- and B-port supply rails (VCCA/VCCB), each configurable from 1.1V to 5.5V. Data flows unidirectionally-A-to-B or B-to-A-depending on OE logic state and rail referencing, with no internal direction control logic.
Schmitt-trigger inputs provide hysteresis (ΔVT = 0.20–1.18V depending on VCCI) to reject slow edges and noise; integrated static pull-down resistors prevent floating inputs. The VCC isolation (Ioff-float) feature forces all outputs into high-impedance when either VCCA or VCCB falls below 100 mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (per port) | 1.1V to 5.5V - Enables interoperability between legacy 5V logic and modern ultra-low-voltage MCUs (1.1V/1.2V cores). |
| Max Data Rate | 200 Mbps (3.3V→5.0V) - Supports high-speed serial interfaces including fast UART and SPI without timing margin loss. |
| Input Hysteresis (ΔVT) | 0.20–1.18 V - Rejects >100 mV noise on slow-switching signals (e.g., mechanical switches, long traces). |
| Output Drive Strength | ±12 mA at 5V - Sufficient to directly drive LEDs, buffers, or moderate-capacitance buses without external amplification. |
| Ioff-float Current | ≤2.5 µA (–40°C to 125°C) - Ensures safe partial-power-down operation during system sleep modes with no backfeed risk. |
| ESD Protection | ±2500 V HBM, ±1500 V CDM - Meets industrial-grade ESD robustness requirements without external protection diodes. |
| Operating Temperature | –40°C to +125°C - Qualified for under-hood automotive and industrial control environments. |
Pinout & Package
RUT package: 12-pin UQFN (2.00 mm × 1.70 mm), thermally enhanced with exposed pad (recommended grounded). Pin count and layout optimized for space-constrained PCBs in portable and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A4 | Input (A-port) | Referenced to VCCA; accept 1.1V–5.5V logic levels; include weak pulldown to prevent floating. |
| B1Y–B4Y | Output (B-port) | Referenced to VCCB; 3-state controlled by OE; Schmitt-triggered input path ensures clean output transitions. |
| OE | Active-high output enable | Referenced to VCCA or VCCB; drives all Bx outputs to high-Z when low; supports flexible control sourcing. |
| VCCA / VCCB | Independent supply rails | Enable true dual-voltage domain translation; each rail powers its respective I/O bank and internal logic. |
| GND | Ground reference | Common return for both ports; required for proper threshold referencing and ESD path integrity. |
| Thermal Pad | Thermal & electrical connection | Exposed copper pad beneath die; grounding improves thermal dissipation and reduces ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail voltage translation | Independent 1.1V–5.5V operation on A and B ports enables seamless interface between disparate logic families (e.g., 1.2V FPGA ↔ 3.3V sensor). |
| Schmitt-trigger inputs | Configurable hysteresis (0.20–1.18V) eliminates metastability and chatter from noisy or slow-rising signals like switch debouncing or long cable runs. |
| VCC isolation (Ioff-float) | Automatic high-Z output disable when either VCCA or VCCB drops below 100 mV prevents backdrive and bus contention during power sequencing or fault conditions. |
| OE referenced to either rail | Control signal can be sourced from VCCA or VCCB domain - eliminates need for external level-shifting of enable lines. |
| Low quiescent current | 2.5 µA max at 25°C - minimizes standby power in battery-operated IoT nodes and always-on monitoring systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXU0104PW | Same core functionality but in 14-pin TSSOP (5.00 mm × 4.40 mm); higher RθJA (135.8°C/W) limits thermal performance in dense layouts. | Preferred for prototyping or manual assembly where larger footprint is acceptable; not suitable for space-constrained automotive modules. | Select TXU0104PW only when board real estate permits and thermal derating margins allow. |
| SN74AVC4T245RUTR | Bus-oriented bidirectional translator with auto-direction sensing; lacks Schmitt triggers and Ioff-float; max 1.8V–3.3V range (no 5V support). | Applicable only in 3.3V↔1.8V bidirectional data buses (e.g., memory expansion); unsuitable for 5V interfaces or noisy single-ended control lines. | Choose SN74AVC4T245RUTR only for compact bidirectional applications within 1.8V–3.3V domain; avoid for 5V or noise-immune designs. |
Compared with TXU0104PW and SN74AVC4T245RUTR, the TXU0104RUTR uniquely combines ultra-small UQFN packaging, full 1.1V–5.5V dual-rail flexibility, Schmitt-trigger noise immunity, and VCC-disconnect safety - making it the sole option for miniaturized, mixed-voltage, high-reliability embedded systems requiring guaranteed high-Z fail-safe behavior.

FAQ
What is the maximum supported data rate for TXU0104RUTR in a 3.3V-to-5.0V translation configuration?
The TXU0104RUTR supports up to 200 Mbps in 3.3V-to-5.0V up-translation mode, as specified in the switching characteristics table (Section 5.6). This performance is validated across the full –40°C to +125°C operating range with defined setup/hold and propagation delay margins.
Does TXU0104RUTR support bidirectional data flow?
No, TXU0104RUTR is a fixed-direction translator: data flows either A-to-B or B-to-A depending on OE logic state and supply rail assignment, but not simultaneously in both directions. Direction is statically configured at design time-not dynamically sensed like bus transceivers.
How does the Ioff-float feature function in TXU0104RUTR during partial power-down?
When either VCCA or VCCB drops below 100 mV, the TXU0104RUTR automatically disables all outputs and places them in high-impedance state-preventing back-current flow, bus contention, or unintended logic states. This behavior is intrinsic to the silicon and requires no external control.
Can the OE pin of TXU0104RUTR be driven from the VCCB rail instead of VCCA?
Yes, the OE pin in TXU0104RUTR is rail-agnostic: it accepts logic-high signals referenced to either VCCA or VCCB, eliminating the need for external level-shifting circuitry and simplifying control architecture in asymmetric voltage systems.
What is the input hysteresis (ΔVT) of TXU0104RUTR at 1.8V supply, and why does it matter?
At VCCI = 1.8V, TXU0104RUTR provides ΔVT = 0.30–0.55 V (typical), which rejects noise spikes up to ~400 mV and stabilizes marginal input edges-critical for reliable operation with mechanical switches, long cables, or unshielded industrial sensors where signal integrity cannot be guaranteed.
