Product Overview

The LTC4300A-1IMS8#PBF is a 2-wire hot swappable Bus Buffer allows I/O card insertion into a live backplane without corruption of the data and clock busses. When the connection is made, it provides 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. During insertion, the SDA and SCL lines are precharged to 1V to minimize bus disturbances. The LTC4300A-1 incorporates a CMOS threshold digital ENABLE input pin, which forces the part into a low current-mode when driven to ground and sets normal operation when driven to VCC. It also includes an open drain READY output pin, which indicates that the backplane and card sides are connected together. Both the backplane and card may be powered with supply voltages ranging from 2.7 to 5.5V, with no constraints on which supply voltage is higher.
  • 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
  • Supports clock stretching, arbitration and synchronization
