ADM2567EBRNZ

ADM2567E is a 3KV rms signal and power isolated RS-485 transceiver. This device is designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). The device pass radiated emissions testing to the EN 55032 class B standard with margin on a 2-layer printed circuit board (PCB) using two small external 0402 ferrites on isolated power and ground pins. The device features an integrated, low electromagnetic interference (EMI), isolated DC-to-DC converter, which eliminates the need for an external isolated power supply. The device also features cable invert pins, allowing the user to quickly correct reversed cable connection on the A, B, Y, and Z bus pins while maintaining full receiver fail-safe performance. Typical applications are heating, ventilation, and air conditioning (HVAC) networks, industrial field buses, building automation, utility networks, energy meters.

• Cable invert smart feature, ESD protection on RS-485 A, B, Y and Z pins
• ≥±12KV IEC61000-4-2 contact discharge, ≥±15KV IEC61000-4-2 air discharge
• PROFIBUS compliant for 5V VISO, full hot swap support (glitch free power-up/power-down)
• Short-circuit, open-circuit, and floating input receiver fail-safe
• Supports 192 bus nodes (72Kohm receiver input impedance), 25Mbps data rate, full duplex
• VCC supply current-unloaded is 46mA max (VSEL=GNDISO (DE=0V), 3V ≤ VCC ≤ 5.5V,-40°C to 105°C)
• Short-circuit current is 100mA (at VO=0V or VIO, active-low RE=0V, 3V ≤ VCC ≤ 5.5V, -40°C to 105°C)
• Common-mode transient immunity is 250KV/µs (VCM ≥ ±1KV)
• 28-lead SOIC-W-FP package
• Temperature rating range from -40°C to +105°C
