PCA9544APW General Description
PCA9544APW is a 4-channel I2C-bus multiplexer from Texas Instruments. It is designed to enable the user to add more I2C devices to an existing I2C bus while minimizing the impact on the bus capacitance. The device features four bidirectional translating switches that allow any I2C-bus device to be connected or disconnected to the bus. The switches are controlled through the I2C bus, providing flexibility in managing multiple devices on the same bus. PCA9544APW operates at a supply voltage range of 2.3V to 5.5V, making it suitable for a wide range of applications. It has a maximum I2C bus frequency of 400 kHz, allowing for high-speed communication between devices. The device also features a low on-resistance of 3.5 ohms, minimizing voltage drops and ensuring efficient communication. Additionally, PCA9544APW has an enable input that allows for software-controlled power savings by disabling the multiplexer when not in use. The device is available in a TSSOP-14 package, making it compact and easy to integrate into existing designs.
