Key Featrues
Wide Voltage Range Compatibility: The TXB0102 supports voltage translation between 1.2 V to 3.6 V on the A port and 1.65 V to 5.5 V on the B port, enabling seamless bidirectional communication across various low-voltage nodes (1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5 V). This versatility makes it ideal for mixed-voltage systems, enhancing design flexibility and reducing the need for multiple level-shifting components.
Auto Direction Sensing: The device features automatic direction sensing, eliminating the need for a direction control signal. This simplifies system design and reduces the complexity of interfacing between different voltage domains, improving overall system efficiency and reliability.
Integrated ESD Protection: With robust ESD protection exceeding industry standards (e.g., 15-kV Human-Body Model on the B port), the TXB0102 ensures reliable operation in harsh environments. This protection minimizes the risk of damage from electrostatic discharge, enhancing the durability and longevity of the device in real-world applications.
Low Power Consumption: The TXB0102 consumes a maximum of 4 µA of current, making it highly energy-efficient. This low power consumption is particularly beneficial for battery-powered or energy-sensitive applications, extending battery life and reducing overall power consumption in the system.
Partial Power-Down Mode Support: The device incorporates Ioff circuitry, which disables outputs during power-down to prevent current backflow. This feature ensures safe operation in partial power-down scenarios, protecting the device from potential damage and improving system reliability in power-cycling applications.
