LTC4300-2 Datasheet Hot Swappable 2-wire Bus Buffers

Manufacturer: Linear Technology (now Analog Devices)

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The LTC®4300 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 LTC4300-1/LTC4300-2 provide bidirectional buffering, keeping the backplane and card capacitances isolated.

Rise time accelerator circuitry* allows the use of weaker DC pull-up currents while still meeting rise time requirements.

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:.
