ADM3064EARZ

Overview

The ADM3064EARZ is a full-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.0 V to 5.5 V and supports a maximum data rate of 500 kbps. The device features an independent VIO logic supply pin, allowing the digital interface to operate at voltages as low as 1.62 V. It provides ±12 kV IEC ESD protection on bus pins and supports hot swap operations without glitches. The component is housed in a 14-lead narrow-body SOIC package and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Full-duplex communication capability with separate driver and receiver channels
• Independent VIO logic supply for flexible low-voltage digital interfacing
• Robust electrostatic discharge protection compliant with IEC standards
• Glitch-free power-up and power-down support for hot swap applications

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 documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements and thermal management needs before procurement. Confirm availability through authorized distributors.

Selection Notes

Select this model when full-duplex operation and low-speed long-cable transmission are required. The independent VIO pin allows connection to logic levels lower than the main supply voltage. Consider the 14-lead SOIC package for board space constraints and thermal performance requirements.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers. It shares core features like ESD protection and hot swap support with other models in the series but is distinguished by its full-duplex architecture and 500 kbps data rate specification.
