The TXB0108PWR from Texas Instruments is an 8-bit bidirectional voltage-level translator designed for multi-voltage digital system applications. It facilitates communication between devices operating at different voltage levels within a range of 1.2V to 3.6V on its A Port and 1.65V to 5.5V on its B Port, ensuring compatibility across diverse digital ecosystems.
Key features include auto-direction sensing, which simplifies design by eliminating the need for direction control signals. The device also offers a VCC isolation feature, putting all outputs in a high-impedance state if either VCC input is at GND, enhancing system safety during power-up or power-down scenarios. Low power consumption (max 4-μA ICC) and support for partial-power-down mode operation contribute to energy-efficient designs.
With robust ESD protection exceeding ±15-kV Human-Body Model on the B Port, the TXB0108PWR ensures reliability and durability in harsh environments, making it suitable for a wide range of applications.
