What are the key features of TXU0102QDCURQ1?
- AEC-Q100 automotive qualification ensures reliable voltage translation across -40°C to 125°C in harsh vehicle environments
- Two unidirectional channels with shared enable-high control simplify logic-level translation between 1.2 V and 5 V domains
- 5 pF specified load capacitance supports high-speed signal translation in compact 8-pin SOT-23 package
What is TXU0102QDCURQ1 used for?
TXU0102QDCURQ1 is designed for automotive body control modules, ADAS sensor interfaces, and infotainment systems that require level translation between 1.8 V microcontrollers and 3.3 V or 5 V peripherals. Its AEC-Q100 qualification and -40°C to 125°C operating range ensure reliable long-term operation in engine compartment and dashboard applications. The enable-high control pin allows the host MCU to power down the translation channels during sleep modes, reducing standby current in low-power automotive electronics.

Frequently Asked Questions
What makes TXU0102QDCURQ1 specifically suited for automotive designs compared to a standard TXU0102 variant?
TXU0102QDCURQ1 carries AEC-Q100 Grade 1 automotive qualification, guaranteeing operation from -40°C to 125°C with reliability screening per JEDEC standards required for passenger-car electronics. Non-automotive variants may only be characterized from 0°C to 85°C, whereas AEC-Q100 Grade 1 ensures consistent 5 pF load performance and 12 mA output current across the full automotive temperature range.
How does the fixed-direction architecture of TXU0102QDCURQ1 differ from bidirectional level shifters like the TXB series?
TXU0102QDCURQ1 translates signals in one fixed direction per channel, eliminating the direction-sensing circuitry needed by bidirectional devices like the TXB0102. This simplification reduces propagation delay and avoids false direction detection on slow-rise signals below 1 V/µs, making TXU0102QDCURQ1 more reliable for open-drain or slow I2C bus lines where TXB devices can misfire.
For a 1.8 V to 3.3 V interface in an ADAS camera module, how many signals can TXU0102QDCURQ1 translate simultaneously?
TXU0102QDCURQ1 translates 2 signals simultaneously, both in the same direction, covering a 2-wire control bus such as UART TX/RX or CS/SCLK in a single 8-pin SOT-23 package. For a 4-wire SPI interface requiring both 1.8 V to 3.3 V and 3.3 V to 1.8 V translation, two TXU0102QDCURQ1 devices with opposite voltage supply connections can cover all 4 lines in under 12 mm² of PCB area.
What is the output current capability of TXU0102QDCURQ1 and how does it drive capacitive bus loads?
TXU0102QDCURQ1 provides a maximum output sink current of 12 mA and is characterized at a 5 pF load capacitance, capable of charging or discharging a 20 pF bus node in under 5 ns for signal integrity on short PCB traces. For higher capacitive loads above 50 pF, a small series termination resistor of 33 Ω limits overshoot while keeping the RC rise time below 5 ns at 3.3 V.
