DS3487N Quad TRI-STATE RS-422 Line Driver For Balanced Data Links

Use DS3487N when you need reliable differential signaling across backplanes or long cable runs. It’s built for RS-422-style balanced transmission, making it a good fit for motor-control cabinets, test equipment, and multi-drop industrial nodes. DS3487N provides four independent line drivers with TRI-STATE control, so you can share a bus and disable outputs cleanly when the node is not active. Inputs are TTL compatible for easy logic interfacing, and the device is designed for fast switching to preserve edge integrity at higher data rates. Keep DS3487N close to the connector and route pairs tightly for best noise immunity. Request a quote for DS3487N.
