ANALOG DEVICES ADM2565EBRNZ-RL7 Transceiver, RS422, RS485, 25 Mbps, 1 Driver, 1 Receiver, 3 to 5.5 V, -40 to 105 °C, WSOIC-28

ADM2565E is a 3KVrms 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 devices 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. Typical applications include heating, ventilation and air conditioning (HVAC) networks, industrial field buses, building automation, utility networks and energy meters.

• High speed 25Mbps data rate
• Flexible power supplies such as input VCC supply of 3 to 5.5V and Logic VIO supply of 1.7 to 5.5V
• VSEL pin to select VISO supply of 5V (VCC <gt/> 4.5V) or 3.3V
• PROFIBUS compliant for 5V VISO
• High common-mode transient immunity of 250KV/µs
• Short-circuit, open-circuit and floating input receiver fail-safe
• Supports 192 bus nodes (72Kohm receiver input impedance)
• Full hot swap support (glitch free power-up/power-down)
• 28 lead WSOIC package
• Operating temperature range from -40°C to 105°C
