LTC4306 - 采用电容缓冲的 4 通道、二线式总线多路复用器

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.
