LTC4300A-1IMS8#PBF General Description

The LTC4300A series hot swappable 2-wire bus buffersallow I/O card insertion into a live backplane withoutcorruption of the data and clock busses. When the connectionis made, the LTC4300A-1/LTC4300A-2 providebidirectional buffering, keeping the backplane and cardcapacitances isolated. Rise-time accelerator circuitry*allows the use of weaker DC pull-up currents while stillmeeting rise-time requirements. During insertion, theSDA and SCL lines are precharged to 1V to minimize busdisturbances.



  • Bidirectional Buffer for SDA and SCL Lines Increases Fanout
  • Prevents SDA and SCL Corruption During Live Board Insertion and Removal from Backplane
  • Isolates Input SDA and SCL Lines from Output
  • Compatible with I2C, I2C Fast Mode and SMBus Standards (Up to 400kHz Operation)
  • Small MSOP 8-Pin Package
  • Low ICC Chip Disable: <1µA (LTC4300A-1)
  • READY Open Drain Output (LTC4300A-1)
  • 1V Precharge on all SDA and SCL Lines
  • Supports Clock Stretching, Arbitration and Synchronization
  • 5V to 3.3V Level Translation (LTC4300A-2)
  • High Impedance SDA, SCL Pins for VCC = 0V


  • Hot Board Insertion
  • Servers
  • Capacitance Buffer/Bus Extender
  • Desktop Computer
