LTC4300A-1 - Hot Swappable 2-Wire Bus Buffers

General Description

The LTC®4300A series hot swappable 2-wire bus buffers allow I/O card insertion into a live backplane without corruption of the data and clock busses.

When the connection is made, the LTC4300A-1/LTC4300A-2 provide bidirectional buffering, keeping the backplane and card capacitances isolated.

Key Features

  • n Bidirectional Buffer for SDA and SCL Lines Increases Fanout n Prevents SDA and SCL Corruption During Live Board Insertion and Removal from Backplane n Isolates Input SDA and SCL Lines from Output n Compatible with I2C, I2C Fast Mode and SMBus Standards (Up to 400kHz Operation) n Low ICC Chip Disable:.
