Product Overview: PCA9646PW,118

The PCA9646PW,118 is a high-performance, quadruple bidirectional translating switch manufactured by NXP Semiconductors, designed for the creation of I2C-bus and SMBus applications. This innovative component allows for the connection of up to four separate I2C or SMBus segments to a primary bus, effectively expanding the capabilities of the system while maintaining signal integrity and compliance with the I2C-bus specification.

Key Features

• Multi-Channel I2C Switch: Equipped with four bidirectional translating switches, the PCA9646PW,118 can connect four downstream channels to a single upstream channel, thus enhancing the flexibility of the I2C-bus design.
• Level Shifting: The device can actively translate between different voltage levels on the I2C-bus, making it suitable for applications that require communication between components operating at different voltages.
• Channel Selection: The selection of active channels is controlled via the I2C-bus, allowing for dynamic configuration based on the system's requirements.
• Isolation: When a channel is not selected, it is isolated from the main bus, preventing data collision and ensuring stable operation of the entire system.
• Low Standby Current: The PCA9646PW,118 has a low standby current, which contributes to the power efficiency of the system it is integrated into.

Applications

The PCA9646PW,118 is ideally suited for a wide range of applications, including but not limited to:

• Server motherboards and computing environments
• Embedded systems and industrial control
• Power management systems
• Consumer electronics

Technical Specifications

• Package: TSSOP16
• Operating Voltage Range: 2.3V to 5.5V
