Product Overview: PCA9544APW/G,118 by NXP Semiconductors

The PCA9544APW/G,118 is a high-quality, versatile I2C-bus switch with an interrupt logic, designed and manufactured by NXP Semiconductors. This integrated circuit is engineered to provide 4 bidirectional translating switches that can be controlled via the I2C-bus, making it an ideal solution for applications that require the connection of multiple I2C devices with the same address or different bus speeds.

Key Features

• Channel Number: The device offers 4 separate I2C-bus channels, each with its own interrupt output.
• Compatibility: It is compatible with I2C-bus and SMBus standards, allowing for seamless integration with a wide range of I2C compatible devices.
• Operating Voltage: The PCA9544APW/G,118 operates within a supply voltage range of 2.3V to 5.5V, making it suitable for various logic level requirements.
• Translation: The switch is capable of translating different voltage levels between the master and slave devices, providing flexibility in mixed-voltage systems.
• Interrupt Logic: Each channel can be enabled with its interrupt logic, ensuring that the master is informed of the interrupt status of each downstream I2C device.
• Package: The device is encapsulated in a TSSOP (Thin Shrink Small Outline Package) with 20 leads, providing a compact footprint for space-constrained applications.

Applications
