ANALOG DEVICES ADM3095EARZ RS485 Transceiver, 2.5Mbps, Idle, Open, Short, 3 to 5.5V, -40°C to 85°C, NSOIC-16

ADM3095EARZ is a level 4 EMC protected RS-485 transceiver with full ±42V fault protection. This device is designed to withstand overvoltage faults, such as short circuits directly to power supplies, and overvoltage faults, such as ±24V AC supplies connected in error to the RS-485 A and B bus pins. It is an RS-485 transceiver that integrates IEC 61000-4-5 Level 4 surge protection, allowing upto ±4kV protection on the RS-485 bus pins. This device has IEC 61000-4-4 Level 4 electrical fast transient (EFT) protection of up to ±2kV, and IEC 61000-4-2 Level 4 electrostatic discharge (ESD) protection on the bus pins, allowing the device to withstand up to ±15KV on the transceiver interface pins without latch-up or damage. It is used in applications such as heating ventilation and air conditioning (HVAC) networks, industrial field buses, building automation, and utility networks.
