High Speed, Half-Duplex iCoupler Isolated RS-485 Transceiver ADM2486 FEATURES APPLICATIONS Isolated RS-485/RS-422 interfaces PROFIBUS networks Industrial field networks Multipoint data transmission systems GENERAL DESCRIPTION FUNCTIONAL BLOCK DIAGRAM VDD2 VDD1 ADM2486 DE TxD PV RxD BUS SIDE GALVANIC ISOLATION RTS LOGIC SIDE A B RE GND2 GND1 04604-001 Half-duplex, isolated RS-485 transceiver PROFIBUS® compliant ANSI EIA/TIA 485-A and ISO 8482: 1987(E) compliant 20 Mbps data rate 5 V or 3 V operation (VDD1) High common-mode transient immunity: >25 kV/μs Isolated DE status output Receiver open-circuit, fail-safe design Thermal shutdown protection 50 nodes on bus Safety and regulatory approvals UL recognition—2500 VRMS for 1 minute per UL 1577 CSA Component Acceptance Notice #5A VDE Certificate of Conformity DIN EN 60747-5-2 (VDE 0884 Part 2): 2003-01 DIN EN 60950 (VDE 0805): 2001-12; EN 60950: 2000 VIORM = 560 V peak Operating temperature range: −40°C to +85°C Wide body, 16-lead SOIC package Figure 1. The ADM2486 driver has an active-high enable feature. The driver differential outputs and the receiver differential inputs are connected internally to form a differential input/output port that imposes minimal loading on the bus when the driver is disabled or when VDD1 or VDD2 = 0 V. Also provided is an active-high receiver disable feature that causes the receive output to enter a high impedance state. The device has current-limiting and thermal shutdown features to protect against output short circuits and situations where bus contention may cause excessive power dissipation. The part is fully specified over the industrial temperature range and is available in a 16-lead, wide body SOIC package. The ADM2486 differential bus transceiver is an integrated, galvanically isolated component designed for bidirectional data communication on multipoint bus transmission lines. It is designed for balanced transmission lines and complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E). The device employs Analog Devices iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, and a differential input receiver into a single package. The logic side of the device is powered with either a 5 V or a 3 V supply, and the bus side uses an isolated 5 V supply. Rev.
