Analog Devices

The ADM307xE are 3.3 V, low power data transceivers with ±15 kV ESD protection suitable for full- and half-duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission, and they comply with TIA/EIA standards: RS-485 and RS-422.The devices have a ⅛ unit load receiver input impedance, which allows up to 256 transceivers on a bus. Because only one driver should be enabled at any time, the output of a disabled or powered-down driver is tristated to avoid overloading the bus.The receiver inputs have a true fail-safe feature, which eliminates the need for external bias resistors and ensures a logic high output level when the inputs are open or shorted. This guarantees that the receiver outputs are in a known state before communication begins and when communication ceases.ApplicationsPower/energy meteringIndustrial controlLighting systemsTelecommunicationsSecurity systemsInstrumentation

The ADM3095E is a 3.0 V to 5.5 V, 2.5 Mbps, RS-485 transceiver that features up to ±42 V ac/dc peak bus overvoltage fault protection on the RS-485 bus pins. This device is designed to withstand overvoltage faults, such as short circuits directly to power supplies, and overvoltage faults, such as ±24 V ac supplies connected in error to the RS-485 A and B bus pins. The ADM3095E is an RS-485 transceiver that integrates IEC 61000-4-5 Level 4 surge protection, allowing up to ±4 kV protection on the RS-485 bus pins. The device has IEC 61000-4-4 Level 4 electrical fast transient (EFT) protection up to ±2 kV, and IEC 61000-4-2 Level 4 electrostatic discharge (ESD) protection on the bus pins, allowing the device to withstand up to ±15 kV on the transceiver interface pins without latch-up or damage.This device has an extended common-mode input voltage range of ±25 V to improve data communication reliability in noisy environments over long cable lengths where ground loop voltages are possible. The combination of extended common-mode input voltage range, overvoltage fault protection, surge protection, EFT protection, and ESD protection make the ADM3095E a completely integrated electromagnetic compatibility (EMC) protected RS-485 transceiver.The ADM3095E also features a logic supply pin, VIO, for a flexible digital interface, operational to voltages as low as 1.62 V. The ADM3095E is PROFIBUS®compliant with a high driver differential output voltage, VOD, of 2.1 V minimum at power supply voltages greater than 4.5 V. The device is fully characterized over extended operating temperature ranges, with options of −40°C to +125°C, and is available in a 16-lead, narrow body SOIC package..ApplicationsHeating ventilation and air conditioning (HVAC) networksIndustrial field busesBuilding automationUtility networks
