TXS0102QDCURQ1 2-bit bidirectional voltage-level translator
The TXS0102QDCURQ1 from Texas Instruments is an automotive-grade, 2-bit bidirectional voltage-level translator specifically designed to interface between devices operating at different voltage levels in mixed-voltage systems. This AEC-Q100 qualified device, housed in an 8-pin VSSOP package, features two independent configurable channels that can seamlessly translate voltages between various logic levels, supporting translation from 1.2V to 3.6V on the A port and 1.65V to 5.5V on the B port. The translator utilizes a pass-gate architecture with integrated edge-rate accelerators to ensure high-speed data transmission while preventing latch-up issues, making it ideal for automotive applications such as infotainment systems, advanced driver-assistance systems (ADAS), and body electronics where reliable communication between processors, sensors, and peripherals with different I/O voltages is critical.
TXS0102QDCURQ1 Key Features
This voltage-level translator requires no direction control signal, enabling fully automatic bidirectional operation that simplifies system design and reduces component count. The device features a high data rate capability of up to 100 Mbps for push-pull applications and 24 Mbps for open-drain configurations, ensuring compatibility with various communication protocols including I²C, SPI, and UART. The integrated edge-rate accelerators enhance switching speed while maintaining signal integrity, and the robust ESD protection exceeds 8 kV HBM per AEC-Q100 standards, providing excellent reliability in harsh automotive environments. With a low 3.5 μA maximum standby current and wide operating temperature range of -40°C to +125°C, the TXS0102QDCURQ1 delivers optimal performance while minimizing power consumption in always-on systems. The device also includes partial-power-down protection that ensures I/O ports remain in high-impedance state when either VCCA or VCCB is powered down.
