Description

Product Overview: Texas Instruments PCA9547D

The PCA9547D is a high-quality, 8-channel I2C-bus multiplexer designed by Texas Instruments (TI), a leader in semiconductor solutions. This integrated circuit (IC) allows a single host controller to interface with up to eight separate I2C devices that have the same address, effectively extending the capabilities of I2C communication buses. It is particularly useful for applications where multiple identical devices need to be controlled or monitored without address conflicts.

Key Features

  • Channel Selection: The PCA9547D offers eight bidirectional translating switches that can be controlled via the I2C bus, allowing for seamless communication with any of the eight I2C slave devices.
  • Low Standby Current: The device is designed to consume minimal power, with a low standby current, making it suitable for power-sensitive applications.
  • Wide Operating Voltage Range: This multiplexer operates over a wide voltage range from 2.3V to 5.5V, providing flexibility for various system designs and ensuring compatibility with both standard and low-voltage I2C interfaces.
  • High Noise Immunity: The PCA9547D is equipped with integrated glitch filters on the I2C bus inputs, providing enhanced noise immunity and improving the reliability of communications.
  • Interrupt Function: An interrupt input is also included, which allows the downstream I2C devices to flag an interrupt to the host controller, ensuring prompt attention to critical events.

Applications

The versatility of the PCA9547D makes it an excellent choice for a wide range of applications, including:

  • Server and telecommunications
  • Industrial control systems
  • Medical equipment
  • Consumer electronics

Package and Quality

The PCA9547D comes in a compact 24-pin TSSOP (Thin Shrink Small Outline Package), which is suitable for space-constrained applications. TI's commitment to quality ensures that this IC meets the stringent requirements for industrial and commercial temperature ranges, providing reliable performance across various environments.

For designers and engineers looking to incorporate multiple I2C devices within their systems, the PCA9547D multiplexer from Texas Instruments offers a robust and versatile solution that simplifies design complexity and enhances system functionality.
