The ADM2795E is a 5 kV rms signal isolated RS-485 transceiver that features up to ±42 V of ac/dc peak bus overvoltage fault protection on the RS-485 bus pins. The device integrates Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, RS-485transceiver, and IEC electromagnetic compatibility (EMC) transient protection in a single package. The ADM2795E is aRS-485/RS-422 transceiver that integrates IEC 61000-4-5 Level 4surge protection, allowing up to ±4 kV protection on the RS-485bus pins (A and B). The device has IEC 61000-4-4 Level 4 EFTprotection up to ±2 kV and IEC 61000-4-2 Level 4 ESD protection on the bus pins, allowing this device to withstand up to ±15 kV on the transceiver interface pins without latching up. This device has an extended common-mode input range of ±25 V to improve data communication reliability in noisy environments. TheADM2795E is capable of operating over wide power supply ranges, with a 1.7 V to 5.5 V VDD1 power supply range, allowing interfacing to low voltage logic supplies. The ADM2795E is also fully TIA/EIA RS-485/RS-422 compliant when operated over a3 V to 5.5 V VDD2 power supply. The device is fully characterizedover an extended operating temperature range of −40°C to +125°C,and is available in a 16-lead, wide-body SOIC package.
