ADM3064EARZ-R7

Overview

The ADM3064EARZ-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 integrated IEC 61000-4-2 electrostatic discharge protection rated at ±12 kV for both contact and air discharge on the bus pins. A dedicated VIO logic supply pin allows flexible digital interface compatibility, supporting voltages from 1.62 V to 5.5 V. The component is housed in a 14-lead narrow-body SOIC package and is designed for operation across an extended temperature range.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm packaging configuration and reel specifications. Ensure that the selected variant matches the required thermal grade and package dimensions for the target PCB layout. Cross-reference the part number with current datasheet revisions to validate all electrical parameters before finalizing procurement orders.

Selection Notes

Select this model when full-duplex RS-485 communication is required alongside robust ESD protection for industrial environments. The inclusion of a separate VIO supply pin makes it suitable for systems where the logic voltage differs from the main power supply. Consider the 14-lead SOIC package constraints and verify that the 500 kbps data rate aligns with the application's bandwidth requirements.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers, which provides various combinations of duplex modes and data rates. The ADM3064E specifically offers full-duplex operation with a 500 kbps data rate and includes the VIO logic supply feature. It shares common architectural elements with other family members but is distinct in its duplex configuration and speed capabilities.

FAQ

Does the ADM3064E support PROFIBUS?

Yes, the ADM3064E is PROFIBUS compliant when the VCC supply voltage is greater than or equal to 4.5 V.

What is the purpose of the VIO pin?

The VIO pin provides a separate logic supply input, allowing the digital interface to operate independently of the main VCC supply, with a minimum voltage of 1.62 V.

How does the device handle bus faults?

The receiver includes fail-safe circuitry that guarantees a logic high output when inputs are shorted, open, or idle. Additionally, a thermal shutdown circuit protects the driver during excessive power dissipation caused by short circuits.
