Overview of PCA9547D,118

The PCA9547D,118 is a high-performance, 8-channel I2C-bus multiplexer designed by NXP Semiconductors. This versatile integrated circuit (IC) allows for the connection of up to eight I2C devices to a single I2C bus, effectively expanding the number of devices that can be controlled within a system. The PCA9547D,118 is particularly useful in applications where there are address conflicts or when more I2C devices are needed than can be supported by the I2C bus specification.

Key Features

• Channel Selection: The PCA9547D,118 allows the user to select any combination of its eight I2C-bus slave channel inputs via an I2C-bus master.
• Low Standby Current: The device is optimized for low power consumption, which makes it suitable for battery-powered and energy-efficient applications.
• High Noise Immunity: With built-in noise filtering, the IC ensures reliable operation even in environments with electrical noise.
• Wide Operating Voltage Range: It operates across a wide voltage range from 2.3V to 5.5V, making it compatible with a variety of logic levels and supply voltages.

Applications

The PCA9547D,118 is ideal for a multitude of applications, including:

• Servers
• Telecommunications
• Industrial Control Systems
• Medical Equipment
• Consumer Electronics

Technical Specifications

• Package: The device is available in a SOIC-24 package, which is suitable for surface mount technology (SMT).
• Channels: It features 8 bidirectional translating switches that can isolate I2C-bus capacitance, allowing for higher total bus capacitance and longer I2C bus length.
• Interrupt Function: An interrupt input is also provided for each of the eight channels, which can be used to alert the I2C-bus master when an input status has changed.
