Description and Introduction

2-channel I2C switch with interrupt logic and reset The **PCA9543PW** from Philips is a dual bidirectional I²C-bus multiplexer designed to enable communication between multiple I²C devices on a single bus. This component is particularly useful in systems where multiple I²C slave devices share the same address, allowing a master device to select between different bus segments.  

Featuring two bidirectional channels, the PCA9543PW provides a seamless way to expand I²C connectivity while maintaining signal integrity. It operates with a supply voltage range of 2.3V to 5.5V, making it compatible with a variety of logic levels. The device supports standard (100 kHz) and fast-mode (400 kHz) I²C protocols, ensuring flexibility in different applications.  

Key benefits include low on-state resistance, minimal propagation delay, and support for hot insertion, which enhances system reliability. The PCA9543PW also incorporates interrupt inputs, allowing efficient handling of events from downstream devices.  

Packaged in a TSSOP-16 form factor, this multiplexer is ideal for space-constrained designs. Common applications include industrial control systems, embedded computing, and consumer electronics where multiple I²C peripherals must coexist on a single bus.  

With its robust performance and ease of integration, the PCA9543PW is a reliable solution for managing I²C communication in complex electronic systems.
