PCA9544ARGYR  

Specialized Backplane Connectors

The PCA9544ARGYR is a 4-channel I2C switch from Texas Instruments. It is designed to allow multiple I2C devices to share a single I2C bus, which can help reduce the number of I/O pins required on a microcontroller or other system.

Key Features:

• 4-channel I2C switch
• Supports I2C standard mode (100kHz) and fast mode (400kHz)
• Supports hot-swapping of devices on the I2C bus
• Supports bus voltages from 2.7V to 5.5V
• Small 16-pin QFN package

Applications:

The PCA9544ARGYR is suitable for a wide range of applications where multiple I2C devices need to share a single bus. Some potential applications include:

• Industrial control systems
• Automotive infotainment systems
• Consumer electronics
• Sensor networks
• Home automation systems

Overall, the PCA9544ARGYR is a versatile and reliable I2C switch that can help simplify system design and reduce the number of I/O pins required. Its small footprint and support for hot-swapping make it well-suited for a wide range of applications.
