5.7 kV RMS Signal and Power Isolated RS-485 Transceiver with 15 kV IEC ESD Data Sheet ADM2867E/ADM2865E/ADM2863E/ADM2861E FEATURES GENERAL DESCRIPTION 5.7 kV rms isolated RS-485/RS-422 transceiver The ADM2861E, ADM2863E, ADM2865E, and ADM2867E Low radiated emissions, integrated, isolated dc-to-dc are 5.7 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 12 kV IEC61000-4-2 contact discharge electromagnetic interference (EMI), isolated dc-to-dc 15 kV IEC61000-4-2 air discharge converter, which eliminates the need for an external isolated High speed 25 Mbps data rate (ADM2865E/ADM2867E) power supply. The isolation barrier provides immunity to Low speed 500 kbps data rate for EMI control system level electromagnetic compatibility (EMC) standards. (ADM2861E/ADM2863E) The family of isolator devices features 12 kV contact and 15 kV Flexible power supplies air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and Input VCC supply of 3 V to 5.5 V Z pins. The devices also features cable invert pins, allowing the user Logic VIO supply of 1.7 V to 5.5 V to quickly correct reversed cable connection on the A, B, Y, and VSEL pin to select VISO supply of 5 V (VCC > 4.5 V) or 3.3 V Z bus 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.
