Overview
The ADM3065EARMZ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. It supports data rates up to 50 Mbps and operates within a supply voltage range of 3.0 V to 5.5 V. The device features ±12 kV IEC ESD protection on bus pins, full hot swap support, and receiver fail-safe capabilities. It utilizes an 8-lead MSOP package and functions across an extended temperature range from -40°C to +125°C.
Feature Summary
- IEC 61000-4-2 compliant electrostatic discharge protection on bus pins
- Full hot swap capability with glitch-free power-up and power-down
- Receiver fail-safe for short-circuit, open circuit, and bus idle conditions
Applications
- Industrial fieldbuses
- Process control systems
- Building automation networks
- PROFIBUS networks
- Motor control servo drives and encoders
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and interface standards before procurement. Cross-reference datasheet revisions to validate current specifications.
Selection Notes
Select this component for applications requiring high-speed bidirectional communication over multipoint bus lines. Confirm that the 8-lead MSOP footprint aligns with PCB layout constraints. Verify that the operating environment falls within the specified thermal limits for reliable performance.
Part Context
This part belongs to the ADM306xE series of RS-485 transceivers designed for robust industrial communication. It shares core architectural features with other models in the family but is distinguished by its specific speed rating and package configuration.

FAQ
Does the ADM3065EARMZ include a separate VIO logic supply pin?
No, the ADM3065E does not feature a VIO logic supply pin; its logic inputs operate directly at the VCC supply level.
What is the maximum number of transceivers supported on the bus?
The device features a 1/4 unit load input impedance, allowing connection of up to 128 transceivers onto a single bus.
How does the device handle thermal overload during fault conditions?
A thermal shutdown circuit forces the driver output into a high impedance state if significant internal temperature increases are detected.
