PCA9518DBQR TI I2C Hub | 20-SSOP | 5-Channel, Hot-Swap

Product Overview

The PCA9518DBQR from Texas Instruments is a 5-channel I2C hub designed for hot-swap applications. It allows multiple I2C buses to be connected, enabling communication between multiple masters or slaves without bus contention. The device operates at supply voltages from 2.3V to 3.6V and supports standard (100 kHz) and fast (400 kHz) I2C modes. Packaged in a 20-pin SSOP, it is ideal for systems requiring bus expansion or isolation.
