Description and Introduction

4-CHANNEL IC AND SMBus MULTIPLEXER WITH INTERRUPT LOGIC The **PCA9544ADGVR** from Texas Instruments is a versatile, low-voltage, four-channel I²C-bus multiplexer designed to enable communication between multiple I²C devices sharing the same bus. This component is particularly useful in systems where multiple I²C slave devices must be accessed without address conflicts, simplifying complex bus architectures.  

Featuring bidirectional switching, the PCA9544ADGVR allows any of its four downstream channels to be selected individually, ensuring seamless data transfer between the master and the targeted slave device. Its operating voltage range of 1.65V to 5.5V makes it compatible with a wide variety of logic levels, enhancing flexibility in mixed-voltage applications.  

The device includes interrupt logic, enabling efficient handling of multiple peripherals by allowing the master to identify which downstream channel requires attention. Additionally, its small **TVSOP-20** package makes it suitable for space-constrained designs.  

With built-in pull-up resistors on the SCL/SDA lines and robust ESD protection, the PCA9544ADGVR ensures reliable performance in industrial, consumer, and embedded applications. Its low standby current consumption further supports energy-efficient designs.  

Engineers seeking a reliable I²C multiplexer for complex bus management will find the PCA9544ADGVR an effective solution for optimizing system performance while minimizing design complexity.
