TCA4311ADR TI Hot-Swap Controller | 8-SOIC | 2.7V-5.5V, I2C/SMBus

Product Overview

The TCA4311ADR from Texas Instruments is a hot-swappable I2C and SMBus buffer designed to allow insertion and removal of cards in a live backplane without corrupting the bus. It provides bidirectional buffering, keeping the bus capacitance isolated and preventing glitches during hot-swap events. The device operates from 2.7V to 5.5V and supports standard and fast mode I2C (up to 400 kHz).
