ADM3064EBRZ-R7

Overview

The ADM3064EBRZ-R7 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 IEC 61000-4-2 electrostatic discharge protection rated at ±12 kV for both contact and air discharge, alongside HBM ratings exceeding ±30 kV. A dedicated VIO logic supply pin allows flexible digital interface operation down to 1.62 V. Packaged in a 14-lead narrow-body SOIC, it accommodates an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Full duplex RS-485 communication capability with integrated IEC ESD protection on bus pins
• Flexible digital interface enabled by a separate VIO logic supply pin supporting low-voltage logic levels
• Hot swap support ensuring glitch-free power-up and power-down sequences without bus contention

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 reel specifications. Confirm that the component meets all required environmental and electrical standards for the intended deployment environment before finalizing procurement decisions.

Selection Notes

Select this model when full-duplex communication is required alongside robust ESD protection for industrial environments. Ensure the system design accommodates the separate VIO logic supply if interfacing with lower voltage logic controllers. Verify thermal management requirements given the extended temperature range capabilities.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for high reliability in harsh industrial settings. The series differentiates models based on duplex configuration and data speed, with the ADM3064E specifically providing full-duplex functionality at 500 kbps speeds suitable for long cable runs.
