Product details
Overview
TXU0102QDTTRQ1 from Texas Instruments is an automotive-grade, 2-bit fixed-direction voltage-level translator with Schmitt-trigger inputs and 3-state outputs. It supports dual-rail operation (1.1 V–5.5 V per port), delivers up to 200 Mbps (3.3 V → 5.0 V), provides 12 mA drive strength at 5 V, and operates across –40°C to +125°C for use in automotive infotainment and body control modules.
For engineers reviewing the TXU0102QDTTRQ1 datasheet, TXU0102QDTTRQ1 pinout, TXU0102QDTTRQ1 application, or TXU0102QDTTRQ1 equivalent, this page delivers verified electrical specs, validated pin functions, confirmed AEC-Q100 qualification, and real-world level-shifting use cases including UART/SPI interface bridging between 1.8 V microcontrollers and 3.3 V sensors.
Technical Context
The TXU0102QDTTRQ1 implements a noninverting, fixed-direction translation architecture where A-port signals (A1/A2) referenced to VCCA are translated to B-port outputs (B1Y/B2Y) referenced to VCCB - or vice versa - under OE control. Direction is fixed per channel but configurable via external wiring, not internal logic.
Its Schmitt-trigger inputs provide hysteresis (ΔVT = 0.2–1.18 V depending on supply), enabling robust noise immunity for slow-switching or noisy signals like mechanical switch debouncing. The VCC isolation feature disables all outputs into high-impedance when either VCCA or VCCB falls below 100 mV, supporting safe partial-power-down sequencing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCCA/VCCB) | 1.1 V to 5.5 V per rail - enables interoperability between legacy 5 V, modern 1.2 V/1.8 V logic, and mixed-voltage automotive subsystems. |
| Max Data Rate | 200 Mbps (3.3 V → 5.0 V) - supports high-speed UART, SPI, and JTAG interfaces without timing bottlenecks. |
| Drive Strength | ±12 mA at 5 V - sufficient to directly drive LEDs, small relays, or capacitive loads up to ~15 pF without external buffers. |
| Quiescent Current | 2.5 µA max at 25°C - minimizes standby power in always-on vehicle modules such as door controllers or telematics gateways. |
| Input Hysteresis | 0.2–1.18 V (ΔVT) - rejects noise spikes ≤100 ns and stabilizes transitions on slow-rising signals like thermistor-based sensor lines. |
| Operating Temp | –40°C to +125°C - qualified per AEC-Q100 Grade 1, suitable for under-hood and cabin-located ECUs. |
| ESD Rating | ±2500 V HBM, ±1500 V CDM - meets automotive ESD robustness requirements for assembly and field operation. |
Pinout & Package
TXU0102QDTTRQ1 is packaged in an 8-pin VSSOP (DCU) with nominal body size 2.30 mm × 2.00 mm, optimized for space-constrained automotive PCBs and compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1, A2 | Data inputs referenced to VCCA | Accept logic signals from low-voltage MCU I/O (e.g., 1.8 V ARM core) while isolating VCCA domain from VCCB noise. |
| B1Y, B2Y | Data outputs referenced to VCCB | Deliver clean, rail-to-rail translated outputs to higher-voltage peripherals (e.g., 3.3 V CAN transceivers or display drivers). |
| OE | Output enable (active-high, referenced to VCCA or VCCB) | Enables/disables both outputs simultaneously; floating or pulled to GND ensures safe high-Z state during power sequencing. |
| VCCA, VCCB | Independent supply rails | Allow asymmetric voltage translation (e.g., 1.2 V → 5.0 V) without level-shifter biasing components or external regulators. |
| GND | Common reference | Single ground connection required - no separate analog/digital grounds needed, simplifying layout in cost-sensitive modules. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Eliminates need for external RC filtering on noisy or slow-switching lines (e.g., ignition sense, door latch feedback). |
| VCC isolation (Ioff-float) | Prevents back-powering and current leakage when one supply is off - critical for fail-safe behavior in multi-rail automotive domains. |
| Integrated static pull-down resistors | Guarantees defined logic-low state on unconnected inputs, avoiding floating nodes that cause shoot-through or erratic MCU reads. |
| Pinout compatibility with TXB family | Enables drop-in replacement in existing designs using TXB0102 or TXB0104, reducing redesign effort and qualification time. |
| AEC-Q100 Grade 1 qualification | Validated for automotive temperature range and reliability - eliminates need for additional stress testing in Tier 1 production programs. |
Applications
| Automotive Body Control Module | Infotainment System Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXB0102RUGR | Auto-bidirectional (no OE pin); lower max speed (100 Mbps); no Schmitt inputs; same VSSOP-8 package. | Best for simple bidirectional I²C or SMBus links where direction control is unnecessary and noise immunity is secondary. | Select TXB0102RUGR only if automatic direction sensing suffices and Schmitt-trigger noise rejection is not required. |
| SN74AVC2T244QDCURQ1 | Buffer-based (non-translating); fixed 1.8 V/3.3 V supply; no dual-rail flexibility; includes bus-hold circuitry. | Suitable for same-voltage domain fan-out or signal conditioning, not cross-voltage translation. | Choose SN74AVC2T244QDCURQ1 only when translating is not needed and bus-hold functionality is preferred for unused inputs. |
Compared with TXB0102RUGR and SN74AVC2T244QDCURQ1, the TXU0102QDTTRQ1 uniquely combines Schmitt-trigger noise immunity, explicit OE control for deterministic direction, full 1.1 V–5.5 V dual-rail support, and automotive qualification - making it the sole choice for noise-prone, mixed-voltage, safety-critical automotive signal routing.

FAQ
What is the maximum data rate supported by TXU0102QDTTRQ1?
The TXU0102QDTTRQ1 supports up to 200 Mbps when translating from 3.3 V to 5.0 V. Performance varies with supply voltage combinations - e.g., 15 Mbps typical at 1.2 V → 1.8 V - and is specified across –40°C to +125°C. Propagation delay remains under 31 ns in worst-case conditions, enabling reliable high-speed UART and SPI operation.
Does TXU0102QDTTRQ1 require external pull-up or pull-down resistors?
No, TXU0102QDTTRQ1 integrates static pull-down resistors on all inputs (A1, A2, OE), eliminating the need for external biasing. This ensures defined logic states during power-up, power-down, or unconnected inputs - a key advantage in automotive systems where floating nodes can trigger spurious interrupts or latch-up.
Can TXU0102QDTTRQ1 translate signals from a higher voltage to a lower voltage (e.g., 5 V → 1.8 V)?
Yes, TXU0102QDTTRQ1 supports bidirectional fixed-direction translation: A→B or B→A, depending on how VCCA and VCCB are assigned. For 5 V → 1.8 V, connect the 5 V source to VCCB and the 1.8 V domain to VCCA, then route signals from Bx inputs to Ax outputs - verified in the device functional modes table of the datasheet.
Is TXU0102QDTTRQ1 pin-compatible with other TI level shifters?
Yes, TXU0102QDTTRQ1 shares identical pinout and footprint with the TXB0102 family (e.g., TXB0102RUGR) in the VSSOP-8 (DCU) package. This allows direct PCB replacement in existing designs without layout changes - provided OE control and Schmitt-trigger requirements align with the application.
What automotive qualification does TXU0102QDTTRQ1 meet?
TXU0102QDTTRQ1 is qualified to AEC-Q100 Grade 1 (–40°C to +125°C ambient), with tested latch-up immunity (>100 mA per JESD78 Class II) and ESD robustness (±2500 V HBM, ±1500 V CDM). It is manufactured in IATF 16949-certified facilities and supports PPAP documentation for Tier 1 automotive production releases.
