PROFIBUS transceiver ADM2461E series

datafull duplex

5.7 kV rms, signal isolated RS-485/RS-422 transceiver Low radiated emissions, passes EN55032 Class B with margin on a 2-layer PCB Cable inversion smart feature Correction for reversed cable connection on A, B, Y, and Z bus pins while maintaining full receiver fail-safe ESD protection on the RS-485 A, B, Y, and Z bus pins ≥±12 kV IEC61000-4-2 contact discharge ≥±15 kV IEC61000-4-2 air discharge Low speed 500 kbps data rate for EMI control Flexible power supply inputs Primary VDD1 supply of 1.7 V to 5.5 V Isolated VDD2 supply of 3.0 V to 5.5 V Profibus® compliant for 5 V VDD2 Wide −40°C to +125°C operating temperature range High common-mode transient immunity: >250 kV/μs Short-circuit, open-circuit, and floating input receiver fail-safe Supports 192 bus nodes (72 kΩ receiver input impedance) Full hot swap support (glitch free power-up and power-down) Safety and regulatory approvals (pending) CSA Component Acceptance Notice 5A, DIN V VDE V 0884-11, UL 1577, CQC11-471543-2012, IEC 61010-1 16-lead, wide body, SOIC_W package with >8.0 mm creepage and clearance in standard pinout 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.
