The ADM2486 Rev. C is an half-duplex isolated RS-485 transceiver manufactured by Analog Devices, which complies with ANSI EIA/TIA 485-A and ISO 8482: 1987(E) standards, supports 20 Mbps data rate, operates at 5 V or 3 V, has high common-mode transient immunity (>25 kV/μs), isolated DE status output, open-circuit fault protection, thermal shutdown protection, up to 50 nodes on bus, and has been certified by UL, CSA and VDE. It works in the temperature range of -40°C to +85°C and is packaged in a wide body 16-lead SOIC package.
The ADM2486 is an integrated, galvanically isolated differential bus transceiver designed for bidirectional data communication on multipoint transmission lines. Utilizing Analog Devices' iCoupler technology, it combines a three-channel isolator with a line driver and receiver in a single 16-lead SOIC package.
