Overview

The TXB0106 is a 6-bit, bidirectional voltage-level translator with automatic direction sensing. It allows devices operating at different voltage nodes (e.g., 1.2V to 3.6V on VCCA and 1.65V to 5.5V on VCCB) to communicate seamlessly. With a data rate of 100Mbps, it is suitable for high-speed data transfer between mixed-voltage systems.

Why Choose This Part

This translator offers automatic direction sensing, simplifying design by eliminating the need for an external direction-control pin. Its wide supply voltage ranges for both A and B ports (1.2V-3.6V and 1.65V-5.5V respectively) provide broad compatibility. The low-power consumption and partial-power-down mode support also contribute to energy efficiency in battery-powered applications.

Applications

I2C and SPI Bus Translation
Enables communication between microcontrollers and peripherals operating at different supply voltages using I2C or SPI protocols.
General Purpose I/O Level Shifting
Translates digital signals for general-purpose input/output lines when interfacing components with varying logic levels.
SD Card Interfaces
Facilitates communication between a host controller and an SD card when they operate at different voltage domains, ensuring signal integrity.
Telecom Equipment
Used in telecommunications systems to bridge different voltage logic families within complex board designs.
Personal Electronics
Integrates components in consumer devices where various sub-systems might operate at different battery or regulated voltages.
