The PCA9546ADWG4 is a quad bidirectional translating switch designed for I¬=C and SMBus applications. It features four downstream channels that can be selected individually or in combination via a programmable control register. The device supports voltage-level translation between 1.8V, 2.5V, 3.3V, and 5V, allowing for compatibility with various bus voltages without additional protection. An active-low reset input enables recovery from low-state conditions on downstream I¬=C buses, ensuring reliable operation. The PCA9546ADWG4 operates within a supply voltage range of 2.3V to 5.5V and is tolerant to 5.5V on all I/O pins. It is suitable for applications in servers, routers, factory automation, and scenarios involving I¬=C slave address conflicts. The device is packaged in a 16-pin SOIC format and is rated for operation between -40¬8C and 85¬8C.
