Product details
Overview
TXS0104EQRUTRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified 4-bit bidirectional voltage-level translator for open-drain and push-pull logic interfaces. It supports 1.65–3.6 V on A port and 2.3–5.5 V on B port (VCCA ≤ VCCB), delivers up to 24 Mbps in push-pull mode, requires no direction-control signal, and integrates 10-kΩ pullups on both ports-enabling I²C and 1-wire level translation in ADAS and infotainment systems.
For engineers reviewing the TXS0104EQRUTRQ1 datasheet, TXS0104EQRUTRQ1 pinout, TXS0104EQRUTRQ1 application, or TXS0104EQRUTRQ1 equivalent, key selection criteria include its auto-direction sensing architecture, dual-rail supply independence, ±8-kV IEC 61000-4-2 ESD protection on B port, guaranteed operation from –40°C to +125°C, and UQFN-12 (2 mm × 1.7 mm) package with thermal pad.
Technical Context
The TXS0104EQRUTRQ1 uses a pass-gate architecture with edge-rate accelerator one-shots per channel to boost low-to-high transition speed without external components. Each A- and B-port I/O includes an integrated 10-kΩ pullup resistor referenced to its respective supply rail (VCCA or VCCB), eliminating external resistors in open-drain applications like I²C.
Its directionless operation relies on internal gate bias control that dynamically enables conduction based on relative voltage slew at either port-no OE-driven state machine or clocked logic is involved. The OE input, referenced to VCCA, places all outputs in high-impedance when pulled low, and requires a pull-down resistor to GND during power sequencing to ensure safe startup.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCCA Range | 1.65 V to 3.6 V - powers A port; must be ≤ VCCB; enables compatibility with 1.8-V/2.5-V/3.3-V logic domains. |
| VCCB Range | 2.3 V to 5.5 V - powers B port; supports 3.3-V/5-V peripherals; enables translation to legacy automotive microcontrollers. |
| Max Data Rate | 24 Mbps (push-pull), 2 Mbps (open-drain) - sufficient for high-speed I²C Fast Mode Plus (1 Mbps) and SPI-like signaling. |
| ESD Protection | ±8-kV contact / ±10-kV air-gap (IEC 61000-4-2, B port); ±2-kV HBM (A port) - meets automotive EMC robustness requirements. |
| Operating Temp | –40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for under-hood and cockpit electronics. |
| Propagation Delay | ≤ 4.4 ns (B→A, VCCA=2.5 V, VCCB=3.3 V, push-pull) - ensures timing integrity in sub-10-ns critical paths. |
| Supply Current | 25 μA typical (ICCA + ICCB) - ultra-low quiescent power for always-on vehicle networks. |
Pinout & Package
TXS0104EQRUTRQ1 is packaged in a 12-pin UQFN (RUT) with 0.4-mm pitch, 2 mm × 1.7 mm footprint, and exposed thermal pad. This compact automotive-grade package supports reflow assembly and provides enhanced thermal dissipation over TSSOP alternatives.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXS0104QPWRQ1 | TSSOP-14 package (5 mm × 6.4 mm); higher RθJA (115.2°C/W); no thermal pad. | Preferred for prototyping or space-tolerant PCBs; less suitable for thermally constrained modules. | Select when board real estate allows larger footprint and thermal performance margin exceeds 20°C/W. |
| SN74AVC4T245QDRQ1 | Direction-controlled (DIR pin required); no integrated pullups; supports 1.2–3.6 V on both sides. | Requires MCU GPIO for direction management; unsuitable for true I²C bidirectional use without external logic. | Choose only if push-pull-only, unidirectional-per-transaction interfaces dominate and lower cost is prioritized. |

FAQ
What voltage ranges does the TXS0104EQRUTRQ1 support on its A and B ports?
The TXS0104EQRUTRQ1 supports 1.65 V to 3.6 V on the A port (VCCA) and 2.3 V to 5.5 V on the B port (VCCB), with the constraint that VCCA must be ≤ VCCB. This enables translation between common automotive logic domains such as 1.8-V microcontrollers and 5-V sensor interfaces. The device maintains full functionality across this range without external level-shifting components.
Does the TXS0104EQRUTRQ1 require external pullup resistors for I²C operation?
No-the TXS0104EQRUTRQ1 integrates 10-kΩ pullup resistors on both A and B ports, referenced to VCCA and VCCB respectively. This eliminates the need for external pullups in standard I²C open-drain configurations, reducing BOM count and PCB area. The internal resistors are optimized for 2-Mbps I²C Fast Mode Plus timing and meet rise-time specifications across temperature and voltage ranges.
How is the OE pin used in the TXS0104EQRUTRQ1, and what is its voltage reference?
The OE (output-enable) pin of the TXS0104EQRUTRQ1 is an active-low input referenced to VCCA. When pulled low, it places all A- and B-port I/Os in high-impedance state. To ensure safe high-Z behavior during power-up/power-down, OE must be tied to GND via a pull-down resistor-minimum value determined by the driving source's current-sinking capability. OE has ±2 μA input current and operates across the full VCCA range.
What is the maximum data rate supported by the TXS0104EQRUTRQ1 in push-pull versus open-drain modes?
The TXS0104EQRUTRQ1 supports up to 24 Mbps in push-pull mode (e.g., with VCCA = 2.5 V and VCCB = 5 V) and up to 2 Mbps in open-drain mode-consistent across all supported VCCB voltages. These rates are validated per JEDEC JESD68 and reflect worst-case propagation delay (≤4.4 ns) and channel skew (≤1 ns), making it suitable for high-speed diagnostics and burst-mode sensor data transfer in automotive networks.
Is the TXS0104EQRUTRQ1 qualified for automotive applications, and what AEC-Q100 grade does it meet?
Yes-the TXS0104EQRUTRQ1 is AEC-Q100 qualified and rated for Device Temperature Grade 1 (–40°C to +125°C ambient). It also meets HBM ESD Classification Level 2 (±2.5 kV) and CDM Level C6 (±1.5 kV), with additional IEC 61000-4-2 certification (±8-kV contact, ±10-kV air-gap) on the B port. These qualifications are fully documented in TI's SCES853F datasheet revision October 2024.
