Description

The ADM2461E/ADM2463E are 500 kbps, 5.7 kV rms, signal isolated RS-485 transceivers that pass radiated emissions testing to the EN55032 Class B standard with margin on a 2-layer printed circuit board (PCB). The ADM2461E/ADM2463E isolation barrier provides robust immunity to noise and system level EMC events. The devices are protected against ≥±12 kV contact and ≥ ±15 kV air IEC61000-4-2 electrostatic discharge (ESD) events on the RS-485 A, B, Y, and Z pins. The devices feature cable invert pins to allow quick correction of the reversed cable connection on the A, B, Y, and Z bus pins while maintaining full receiver fail-safe performance.These devices are optimized for low speed over long cable runs and have a maximum data rate of 500 kbps. The high differential output voltage makes these devices suitable for Profibus nodes when powered with 5 V on the VDD2supply. The VDD1primary supply and VDD2isolated supply both support a wide range of voltages (1.7 V to 5.5 V and 3 V to 5.5 V, respectively). Half-duplex and full duplex device options are available in the industry standard 16-lead, wide-body, standard SOIC_W package with >8.0 mm creepage and clearance.ApplicationsHeating, ventilation, and air conditioning (HVAC) networksIndustrial field busesBuilding automationUtility networks
