LTC4300A-3 - Level Shifting Hot Swappable 2-Wire Bus Buffer

General Description

The LTC®4300A-3 hot swappable 2-wire bus buffer allows I/O card insertion into a live backplane without corruption of the data and clock busses.

When the connection is made, the LTC4300A-3 provides 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 Logic Threshold ENABLE Input n Isolates Input SDA and SCL Lines From Output n Compatible with I2C, I2C Fast Mode and SMBus Standards (Up to 400kHz Operation) n 1V Precharge on all SDA and SCL Lines n Supports Clock Stretching, Arbitration and Synchronization.
  • 5V to 3.3V Level Translation.
  • High Impedance SDA, SCL Pins for VCC = 0V,.
