产品详情

The LTC®4306 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 2.2V 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.

The LTC4306 is available in 24-lead QFN (4mm × 5mm) and SSOP packages.
