ADM2795ETRWZ-EP

ADM2795E-EP is a 5KV rms signal isolated RS-485 transceiver that features up to ±42V 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-485 transceiver, and IEC electromagnetic compatibility (EMC) transient protection in a single package. This integrates fully certified DO-160G EMC protection on the RS-485 bus pins, with section 22 lightning protection. This also provides section 25 ±15KV ESD air discharge protection. This device has an extended common-mode input range of ±25V to improve data communication reliability in noisy environments. This is capable of operating over wide power supply ranges, with a 1.7V to 5.5V VDD1 power supply range, allowing interfacing to low voltage logic supplies. Typical applications are military and aerospace (MILA) avionics for sensors, actuators, and engine control.

• Supports defence and aerospace applications (AQEC standard)
• Controlled manufacturing baseline, 1 assembly/test site
• Enhanced product change notification, glitch free power-up/power-down (hot swap)
• Supports 256 bus nodes (96Kohm receiver input impedance)
• Receiver short-circuit, open-circuit, and floating input fail-safe
• TIA/EIA RS-485/RS-422 compliant over full supply range
• Supply current in shutdown mode is 10mA max (DE=0V, active-low RE=VDD1, TA=−55 to 125°C)
• 16-lead standard small outline package [SOIC-W]
• Temperature rating range from −55°C to +125°C
