The PCA9548APW,118 is a high-quality, 8-channel I2C-bus switch with reset from NXP Semiconductors. This versatile integrated circuit (IC) is designed to enable communication with multiple I2C devices that have the same address, thereby solving the address conflict issues commonly faced in complex I2C systems. It is particularly ideal for applications requiring the interfacing of multiple I2C devices or for expanding I2C bus capabilities.

Key Features

• Multi-Channel I2C Switching: The device features 8 bidirectional translating switches that can be controlled via the I2C bus, allowing for the connection of up to eight separate I2C slave devices.
• Channel Selection: Each switch can be enabled or disabled via I2C commands, providing flexibility and control to the user for selective communication with connected I2C peripherals.
• Low Standby Current: The PCA9548APW,118 is designed with power efficiency in mind, offering a low standby current which makes it suitable for battery-powered and power-sensitive applications.
• Wide Operating Voltage Range: This device operates over a wide voltage range from 2.3V to 5.5V, making it compatible with various logic levels and suitable for mixed-voltage systems.
• High Noise Immunity: With built-in noise filter circuits on the I2C bus input, the PCA9548APW,118 ensures stable operation in environments with electrical noise.
