The PCA9548ADBG4 is a high-quality, 8-channel I2C switch manufactured by Texas Instruments, designed to provide flexible signal routing for I2C and SMBus applications. This device enables communication with multiple I2C devices that have the same address, thus resolving address conflict issues and expanding the number of I2C devices that can be connected in a system.

Key Features

• Channel Number: 8 bidirectional translating switches that can select any combination of I2C-bus and SMBus slave devices.
• Voltage Range: Operates from a 2.3V to 5.5V power supply, making it suitable for a wide variety of applications and logic levels.
• Low Standby Current: Features low standby current, which is essential for power-sensitive designs.
• Interrupt Function: Comes with an interrupt input feature, which allows the master device to be alerted of activity on any of the downstream I2C buses.
• High Noise Filter: Built-in noise filter on the I2C bus and SMBus data lines ensures signal integrity.

Applications

The PCA9548ADBG4 is ideal for applications that require multiple I2C or SMBus devices to be connected to a single I2C bus. It is commonly used in:

• Servers and networking equipment
• Telecommunications
• Consumer electronics
• Industrial control systems
• Medical equipment

Package and Quality

Enclosed in a 20-pin TSSOP (DB) package, the PCA9548ADBG4 is designed to meet the robustness requirements of commercial and industrial temperature ranges. Texas Instruments ensures high manufacturing standards, providing reliability and performance for critical applications.
