The IC component PCA9541APW/03,118 is a low-voltage 2-channel I2C multiplexer manufactured by NXP Semiconductors. It allows multiple I2C devices to be connected to a single I2C bus, effectively expanding the capacity of the bus.
Key Features:
1. I2C Multiplexer: The PCA9541APW/03,118 acts as a multiplexer, enabling the connection of two different I2C buses or segments to a single I2C bus.
2. Flexible Channel Selection: It provides a way to select the active channel through a two-wire serial interface (I2C bus), allowing communication with specific devices connected to that channel.
3. Low Voltage: The device operates at a low voltage range from 1.65V to 5.5V, making it suitable for various low-power applications.
4. High-Speed Operation: It supports high-speed I2C communication, allowing data rates of up to 400 kbit/s, ensuring quick and efficient data transfer between devices.
5. Low Standby Current: The PCA9541APW/03,118 consumes very low power in standby mode, making it energy-efficient and suitable for battery-powered applications.
6. Interrupt Output: It includes an interrupt output pin that can be used to generate an interrupt signal when an I2C channel's state changes, allowing efficient handling of device connections
