DS3487N

The DS3487N is a quad RS-485/RS-422 line driver and receiver IC from Maxim Integrated. It is designed for use in industrial applications that require robust communication over long distances. The DS3487N operates over a wide voltage range of 4.75V to 5.25V and is capable of driving signals up to 80Mbps over twisted-pair cables.The device features four independent drivers and receivers, making it suitable for multi-drop or multidrop applications. It also includes thermal shutdown protection to prevent damage from overheating. The DS3487N is compliant with the EIA/TIA-485-A and EIA/TIA-422-B standards, ensuring compatibility with existing systems.The device incorporates fail-safe circuitry that guarantees a high output state when the input is open or shorted. This feature ensures reliable communication in noisy environments where signal integrity may be compromised.In terms of packaging, the DS3487N is available in a 16-pin PDIP package, making it easy to integrate into existing designs.
