PCA9518DW TI I2C Buffer | 20-SOIC | 5-Channel, Hot-Swap

Product Overview

The PCA9518DW from Texas Instruments is a 5-channel, hot-swappable I2C bus buffer designed to extend the I2C bus capacitance and provide isolation between bus segments. It operates at supply voltages from 2.3V to 3.6V and supports standard (100 kHz) and fast (400 kHz) I2C modes. The device features a built-in rise time accelerator and a logic-controlled enable pin, making it ideal for multi-master and hot-swap applications. Housed in a 20-pin SOIC package, the PCA9518DW offers robust performance for industrial and telecom systems.
