3 kV RMS Signal and Power Isolated RS-485 Transceiver with 15 kV IEC ESD Data Sheet ADM2561E/ADM2563E/ADM2565E/ADM2567E FEATURES GENERAL DESCRIPTION 3 kV rms isolated RS-485/RS-422 transceiver The ADM2561E, ADM2563E, ADM2565E, and ADM2567E Low radiated emissions, integrated, isolated dc-to-dc are 3 kV rms signal and power isolated RS-485 transceivers. converter These devices are designed for balanced transmission lines and Passes EN 55032 Class B with margin on a 2-layer PCB comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). Cable invert smart feature The devices pass radiated emissions testing to the EN 55032 Correct reversed cable connection on A, B, Y, and Z bus Class B standard with margin on a 2-layer printed circuit board pins while maintaining full receiver fail-safe feature (PCB) using two small external 0402 ferrites on isolated power ESD protection on RS-485 A, B, Y and Z pins and ground pins. The device features an integrated, low electro- 12 kV IEC61000-4-2 contact discharge magnetic interference (EMI), isolated dc-to-dc converter, which 15 kV IEC61000-4-2 air discharge eliminates the need for an external isolated power supply. The High speed 25 Mbps data rate (ADM2565E/ADM2567E) isolation barrier provides immunity to system level electromag- Low speed 500 kbps data rate for EMI control netic compatibility (EMC) standards. The family of isolator (ADM2561E/ADM2563E) devices features 12 kV contact and 15 kV air IEC61000-4-2 Flexible power supplies ESD protection on the RS-485 A, B, Y, and Z pins. The devices Input VCC supply of 3 V to 5.5 V also features cable invert pins, allowing the user to quickly Logic VIO supply of 1.7 V to 5.5 V correct reversed cable connection on the A, B, Y, and Z bus VSEL pin to select VISO supply of 5 V (VCC > 4.5 V) or 3.3 V pins while maintaining full receiver fail-safe performance. PROFIBUS compliant for 5 V VISO Slew rate limited versions are available, which are optimized for Wide operating temperature range: 40C to +105C low speed over long cable runs, and have a maximum data rate High common-mode transient immunity: 250 kV/s of 500 kbps. Half duplex and full duplex variants are available. Short-circuit, open-circuit, and floating input receiver fail-safe The full duplex generics allow independent cable inversion of Supports 192 bus nodes (72 k receiver input impedance) the driver and receiver for additional flexibility. Full hot swap support (glitch free power-up/power-down) Table 18 shows the summary description of each generic.
