TCA9546ADR General Description

Ideal for managing multiple I2C buses, the TCA9546ADR is a sophisticated quad bidirectional translating switch that offers unparalleled control over channel routing. By allowing users to fan out the upstream pair to four downstream channels and enabling selective channel activation through the programmable control register, this device provides a high level of customization in routing I2C communication. In case of a stuck I2C bus scenario, the active-low reset input comes to the rescue by resetting the state machine and deselecting all channels, ensuring uninterrupted operation and preventing potential communication disruptions. Moreover, the VCC pin's ability to limit the maximum voltage passed by the TCA9546ADR facilitates seamless integration between components with varying voltage requirements, eliminating the need for additional protection measures. With all I/O pins boasting 5.5-V tolerance, this device guarantees compatibility with a diverse range of systems, making it a reliable choice for complex I2C bus setups
