Product details
Overview
TXU0204QWBQARQ1 from Texas Instruments is an AEC-Q100 qualified automotive 4-bit fixed-direction voltage-level translator with Schmitt-trigger inputs and 3-state outputs, supporting dual-rail operation from 1.1V to 5.5V per port, up to 200Mbps translation (3.3V→5.0V), and operating across –40°C to +125°C for use in engine control units and ADAS sensor interfaces.
For engineers reviewing the TXU0204QWBQARQ1 datasheet, TXU0204QWBQARQ1 pinout, TXU0204QWBQARQ1 application, or TXU0204QWBQARQ1 equivalent, key selection considerations include VCCA/VCCB supply independence, Ioff-float isolation behavior, Schmitt-trigger noise immunity, OE logic referencing flexibility, and wettable flank QFN (WBQA) package compatibility with automated optical inspection.
Technical Context
This device implements a noninverting fixed-direction level-shifting architecture where data flows unidirectionally between A and B ports based on OE state, with each port referenced to its own supply rail (VCCA or VCCB). Inputs feature integrated static pull-down resistors and Schmitt-trigger thresholds (ΔVT ≥ 0.2V) to reject slow edges and noise.
Control logic uses VCC(MIN) circuitry enabling OE to be driven from either VCCA or VCCB, while VCC isolation and Ioff-float functionality disable all outputs into high-impedance when either supply drops below 100mV - critical for partial-power-down modes in automotive domain controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (per port) | 1.1V to 5.5V - enables interoperability between legacy 5V microcontrollers and modern 1.2V/1.8V SoCs without external biasing. |
| Max Data Rate | 200Mbps (3.3V→5.0V) - supports high-speed UART, SPI, and JTAG communication between mixed-voltage subsystems. |
| Input Threshold Hysteresis | ≥0.2V (ΔVT) - ensures robust rejection of EMI-induced glitches on noisy automotive harnesses. |
| Ioff-float Current | ≤±2.5µA (–40°C to 125°C) - guarantees safe high-Z output state during supply sequencing or fault conditions. |
| Drive Strength | ±12mA at 5V - sufficient to directly drive LEDs, buzzers, or logic inputs without external buffers. |
| Quiescent Current | ≤6µA (–40°C to 125°C) - minimizes standby power in always-on vehicle modules like body control units. |
| ESD Rating | ±2500V HBM / ±1500V CDM - meets stringent AEC-Q100 stress requirements for under-hood electronics. |
Pinout & Package
TXU0204QWBQARQ1 is packaged in a wettable flank QFN (WBQA), 14-pin VQFN measuring 3mm × 2.5mm, optimized for solder joint inspection and thermal performance in automotive PCB assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1–A2 | Input (A-port) | Referenced to VCCA; accept 1.1V–5.5V logic levels with Schmitt-trigger hysteresis. |
| A3Y–A4Y | Output (A-port) | Noninverting outputs referenced to VCCA; tri-stated when OE = low. |
| B1Y–B2Y | Output (B-port) | Noninverting outputs referenced to VCCB; direction fixed A→B or B→A per OE configuration. |
| B3–B4 | Input (B-port) | Referenced to VCCB; include internal pull-down to prevent floating in unconnected states. |
| OE | Output Enable | Active-high control referenced to VCCA or VCCB; enables/disables all outputs simultaneously. |
| VCCA / VCCB | Supply Rails | Independent supplies for A and B ports; support asymmetric voltage translation (e.g., 1.8V↔3.3V). |
| GND | Ground | Common reference for both ports; thermal pad recommended grounded for mechanical integrity. |
| NC (pins 6,9) | No Connect | Unbonded pins; must remain unconnected on PCB layout. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs with ≥0.2V hysteresis | Rejects slow-rising signals and EMI noise common in automotive wiring harnesses. |
| VCC isolation and Ioff-float | Automatically places all outputs in high-impedance if either VCCA or VCCB falls below 100mV - prevents backfeeding and supports hot-swap capability. |
| OE referenced to either VCCA or VCCB | Eliminates need for level-shifting the enable signal, simplifying control logic in multi-rail systems. |
| Integrated input pull-down resistors | Prevents undefined logic states on unused or disconnected inputs - reduces external component count and board space. |
| Wettable flank QFN (WBQA) | Enables automated optical inspection (AOI) of solder joints - critical for zero-defect automotive manufacturing standards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage-level translation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TXU0104QWBQARQ1 | All four channels fixed A→B direction; no reverse-path inputs (B3/B4 absent); identical WBQA package and pinout. | Optimized for unidirectional GPIO translation only; lacks bidirectional flexibility of TXU0204QWBQARQ1. | Select when only A→B translation is needed and board space allows same footprint. |
| TXB0104RGERQ1 | Auto-direction sensing architecture; no OE pin; higher typical propagation delay (>15ns vs <10ns for TXU0204QWBQARQ1 at 3.3V→1.8V). | Suitable for bidirectional buses (I²C) but not for controlled-direction protocols like SPI or UART requiring explicit OE control. | Choose for I²C applications; avoid when deterministic enable/disable timing or Schmitt-trigger noise immunity is required. |
Compared with TXU0104QWBQARQ1, TXU0204QWBQARQ1 provides bidirectional channel flexibility (A↔B) and Schmitt-trigger inputs for noisy environments; compared with TXB0104RGERQ1, it offers lower skew, faster enable/disable times, and guaranteed noise immunity - making it preferable for timing-critical automotive serial interfaces.

FAQ
What is the maximum supported data rate for TXU0204QWBQARQ1 in a 3.3V-to-5.0V translation scenario?
TXU0204QWBQARQ1 supports up to 200Mbps in 3.3V-to-5.0V up-translation mode, as specified in the switching characteristics table under TMAX. This performance is validated across the full automotive temperature range (–40°C to +125°C) and assumes proper PCB layout with controlled impedance and minimal stub length.
Does TXU0204QWBQARQ1 support bidirectional data flow between its A and B ports?
TXU0204QWBQARQ1 supports fixed-direction translation only - data flows either A→B or B→A depending on OE configuration and supply referencing, but not simultaneously in both directions. It does not auto-detect direction like TXB-series devices; direction is statically defined by how VCCA, VCCB, and OE are applied in the system design.
How does the Ioff-float feature function in TXU0204QWBQARQ1 during power sequencing?
When either VCCA or VCCB drops below 100mV, TXU0204QWBQARQ1 automatically disables all outputs and forces them into high-impedance state - preventing back-current flow and ensuring safe power-up/down sequencing in multi-rail automotive ECUs. This behavior is guaranteed across –40°C to +125°C and requires no external control.
Can the OE pin of TXU0204QWBQARQ1 be driven from a different voltage domain than VCCA or VCCB?
No - the OE pin of TXU0204QWBQARQ1 must be referenced to either VCCA or VCCB, as confirmed by the functional description and electrical specifications. The VCC(MIN) circuitry ensures correct logic threshold detection regardless of which supply is used, but OE cannot be driven from a third independent voltage rail.
What package variant is designated by the 'WBQA' suffix in TXU0204QWBQARQ1?
The 'WBQA' suffix in TXU0204QWBQARQ1 indicates the wettable flank QFN (VQFN) package - a 14-pin, 3mm × 2.5mm body with exposed thermal pad and flank metallization enabling automated optical inspection (AOI) of solder joints, a requirement for zero-defect automotive manufacturing.
