Product details
Overview
TXU0101QDRYRQ1 from Texas Instruments is an automotive-grade, single-bit fixed-direction voltage-level translator with Schmitt-trigger inputs and 3-state outputs. It operates across dual supplies (VCCA/VCCB = 1.1 V to 5.5 V), supports up to 200 Mbps (3.3 V → 5.0 V), delivers ±12 mA drive strength, features VCC isolation and Ioff-float, and is qualified for –40°C to +125°C operation in automotive systems.
For engineers reviewing the TXU0101QDRYRQ1 datasheet, TXU0101QDRYRQ1 pinout, TXU0101QDRYRQ1 application, or TXU0101QDRYRQ1 equivalent, this device is selected for robust I/O level shifting in noisy, low-voltage automotive domains-especially where slow input edges, partial power-down, or supply rail mismatch must be handled without external pull-ups or timing constraints.
Technical Context
The TXU0101QDRYRQ1 implements a noninverting, unidirectional A→B translation path controlled by a single OE input referenced to either VCCA or VCCB. Its Schmitt-trigger inputs provide hysteresis (ΔVT = 0.2–1.18 V) to reject noise on slow-rising signals, while integrated static pull-down resistors prevent floating inputs during undefined states.
VCC isolation ensures high-impedance outputs when either VCCA or VCCB falls below 100 mV or disconnects. The Ioff-float feature enables partial-power-down mode operation, limiting leakage to ≤2.5 µA over temperature, making it suitable for battery-sensitive automotive subsystems requiring rail sequencing or standby isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCCA/VCCB) | 1.1 V to 5.5 V - Enables interoperability between legacy 5 V, modern 3.3 V/1.8 V/1.2 V logic domains without level-shifting bias networks. |
| Max Data Rate | 200 Mbps (3.3 V → 5.0 V) - Supports high-speed UART, SPI, and JTAG interfaces in automotive control modules. |
| Propagation Delay (tpd) | 8–96 ns (A→B), dependent on VCCA/VCCB - Guarantees deterministic timing for real-time signal bridging with sub-100 ns latency. |
| Drive Strength | ±12 mA at 5 V - Sufficient to directly drive LEDs, buzzer loads, or fanout to multiple CMOS inputs without buffering. |
| Quiescent Current | 2.5 µA max at 25°C - Minimizes standby power in always-on vehicle networks (e.g., CAN wake-up circuits). |
| ESD Rating | ±2500 V HBM, ±1500 V CDM - Meets AEC-Q100 stress requirements for under-hood and infotainment ECU deployment. |
| Operating Temp | –40°C to +125°C - Validated for engine control units, ADAS sensor interfaces, and body electronics mounting locations. |
Pinout & Package
TXU0101QDRYRQ1 is packaged in a 6-pin SON (DRY) package measuring 1.45 mm × 1.00 mm, optimized for space-constrained automotive PCB layouts and thermal performance (RθJA = 279.2°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCCA | A-port supply rail | Reference for input A and OE logic thresholds; sets input voltage domain and internal biasing. |
| GND | Ground reference | Common return path for both supply rails; required for stable threshold referencing and ESD current discharge. |
| A | Data input (A-side) | Schmitt-triggered input referenced to VCCA; accepts 0–VCCA logic levels with hysteresis for noise immunity. |
| BY | Data output (B-side) | 3-state CMOS output referenced to VCCB; driven high/low when OE is high, high-Z when OE is low. |
| OE | Output enable control | Active-high control referenced to VCCA or VCCB; enables/disables BY output; floats to high-Z during power-up if unconnected. |
| VCCB | B-port supply rail | Reference for output BY and OE threshold when OE is tied to VCCB; defines output logic swing and drive capability. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-rail flexibility | Independent VCCA/VCCB from 1.1 V to 5.5 V enables direct interface between disparate logic families (e.g., 1.2 V MCU GPIO to 5 V sensor bus). |
| Schmitt-trigger inputs | Input hysteresis (ΔVT ≥ 0.2 V) rejects noise and accommodates slow mechanical switch transitions or long trace ringing without external RC filtering. |
| VCC isolation & Ioff-float | Outputs go high-Z if either VCCA or VCCB drops below 100 mV; Ioff leakage ≤2.5 µA ensures safe rail sequencing and battery-backed subsystem isolation. |
| OE referenced to either rail | OE can be driven from VCCA or VCCB domain - eliminates need for additional level shifters on the enable line in mixed-supply systems. |
| Automotive qualification | AEC-Q100 Grade 1 certified with latch-up >100 mA and full temperature range validation - suitable for safety-critical powertrain and chassis applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AVC1T45QDRYRQ1 | Bidirectional (auto-sensing) vs. fixed-direction; lower drive (±8 mA); no Schmitt inputs; lacks Ioff-float. | Requires direction-control logic; unsuitable for noisy switch inputs or partial-power-down isolation. | Select only if bidirectional data flow is required and noise immunity is not critical. |
| TXS0101QDRYRQ1 | Auto-direction sensing; weaker drive (±2 mA); no Schmitt inputs; higher quiescent current (10 µA typical). | Cannot handle slow/slew-limited inputs; insufficient for driving LEDs/buzzers; less efficient in ultra-low-power modes. | Prefer only for low-current, bidirectional I²C-like applications where direction control overhead must be avoided. |
Compared with SN74AVC1T45QDRYRQ1 and TXS0101QDRYRQ1, the TXU0101QDRYRQ1 uniquely combines Schmitt-trigger noise rejection, 12 mA drive, and true VCC-isolated Ioff-float - making it the only choice among these three for automotive switch debouncing, high-drive indicator control, and rail-sequenced subsystem isolation.

FAQ
What is the maximum supported data rate for TXU0101QDRYRQ1 in a 3.3 V to 5.0 V translation configuration?
The TXU0101QDRYRQ1 supports up to 200 Mbps when translating from 3.3 V to 5.0 V, as specified in the official datasheet. This performance is validated across the full –40°C to +125°C operating range and assumes proper layout, load capacitance ≤5 pF, and clean supply rails. Real-world throughput may vary based on trace length, termination, and noise coupling - but the 200 Mbps rating reflects worst-case timing margins under AEC-Q100 stress conditions. TXU0101QDRYRQ1 maintains this speed without external components or direction-control logic.
Does TXU0101QDRYRQ1 support bidirectional level translation?
No, TXU0101QDRYRQ1 is a fixed-direction (unidirectional) translator: data flows only from A port to B port when OE is asserted. It does not auto-detect direction or support B→A translation. For bidirectional use cases, TI offers alternatives like TXS0101QDRYRQ1 or SN74AVC1T45QDRYRQ1 - but those lack the Schmitt-trigger inputs and Ioff-float features of TXU0101QDRYRQ1. The fixed-direction architecture of TXU0101QDRYRQ1 simplifies timing analysis and eliminates bus contention risks in automotive control paths.
How does the Schmitt-trigger input on TXU0101QDRYRQ1 improve system reliability?
The Schmitt-trigger input on TXU0101QDRYRQ1 provides programmable hysteresis (ΔVT = 0.2–1.18 V depending on supply) that rejects noise and prevents multiple toggles during slow or oscillatory signal transitions - such as those from mechanical switches, long cables, or unterminated traces. This eliminates the need for external RC filters or firmware debouncing routines. In automotive environments, this directly improves functional safety by ensuring single, deterministic edge detection for critical inputs like brake pedal status or door open/close signals - a key reason TXU0101QDRYRQ1 is AEC-Q100 Grade 1 qualified.
Can TXU0101QDRYRQ1 be used with only one supply rail powered?
Yes - TXU0101QDRYRQ1 includes VCC isolation and Ioff-float functionality. If either VCCA or VCCB drops below ~100 mV or is disconnected, all outputs automatically enter high-impedance state and leakage remains ≤2.5 µA over temperature. This enables safe partial-power-down operation, such as when a sensor subsystem powers down while the host MCU remains active. The OE pin also floats to high-Z during power-up, preventing bus contention. This behavior is explicitly tested and guaranteed per AEC-Q100 requirements - a core differentiator versus generic translators like SN74LVC1T45.
What is the purpose of the integrated static pull-down resistor on the A input of TXU0101QDRYRQ1?
The integrated static pull-down resistor on the A input of TXU0101QDRYRQ1 ensures the input defaults to a known logic-low state when left unconnected or driven by a high-impedance source - preventing floating nodes that could cause erratic output behavior or increased EMI susceptibility. This eliminates the need for external pull-down resistors in applications like switch interfaces or unused GPIO routing. The pull-down is weak enough (leakage <2 µA) to not interfere with active driving, yet strong enough to override noise and meet AEC-Q100 latch-up and ESD robustness requirements. This feature is confirmed in the Electrical Characteristics table under "II Input Leakage Current" for data inputs.
