Product Overview

The LTC4306CGN#PBF is a 4-channel 2-wire Bus Multiplexer with bus buffers to provide capacitive isolation between the upstream bus and downstream buses. Through software control, the LTC4306 connects the upstream 2-wire bus to any desired combination of downstream buses. Each channel can be pulled up to a supply voltage ranging from 2.2 to 5.5V, independent of the LTC4306 supply voltage. The downstream channels are also provided with ALERT1-ALERT4 inputs for fault reporting. Programmable timeout circuitry disconnects the downstream buses if the bus is stuck low. When activated, rise time accelerators source currents into the 2-wire bus pins to reduce rise time. Driving the ENABLE pin low restores all features to their default states. Three address pins provide 27 distinct addresses.
  • Connect SDA and SCL lines with 2-wire bus commands
  • Supply independent bidirectional buffer for SDA and SCL lines increases fan-out
  • Programmable disconnect from stuck bus
  • Rise time accelerator circuitry
  • SMBus compatible ALERT response protocol
  • Two general purpose inputs-outputs
  • Prevents SDA and SCL corruption during live board insertion and removal from backplane
