PCA9545APW,118 - NXP Semiconductors

Manufacturer Part Number

PCA9545APW,118

Manufacturer

NXP Semiconductors

Introduction

The PCA9545APW,118 is a 4-channel I2C/SMBus switch that allows a single I2C or SMBus master to communicate with multiple I2C or SMBus slave devices. It provides four individual bidirectional bus switches, each with its own enable control and interrupt flag. The device can be used to create a hierarchical I2C or SMBus system, allowing the master to access different segments of the bus independently.
