ADM3064EBRZ

Overview

The ADM3064EBRZ 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. It includes a dedicated VIO logic supply pin, allowing digital interface operation down to 1.62 V. The component is housed in a 14-lead narrow-body SOIC package and is designed for extended industrial temperature ranges up to +125°C.

Feature Summary

• Full hot swap support enabling glitch-free power-up and power-down operations without bus contention issues.
• Integrated receiver fail-safe circuitry that guarantees a logic high output when inputs are shorted, open, or idle.
• Thermal shutdown mechanism that forces driver outputs into a high impedance state upon detecting excessive internal temperatures.

Applications

• Industrial fieldbus networks
• Process control systems
• Building automation infrastructure
• PROFIBUS communication networks

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Confirm RoHS compliance status through current datasheets before finalizing procurement specifications.

Selection Notes

Select this model for applications requiring full-duplex communication with flexible low-voltage logic interfacing capabilities. Ensure the system design accommodates the 14-lead SOIC footprint and provides adequate thermal management for the specified operating conditions.

Part Context

This component belongs to the ADM306xE series of RS-485 transceivers. It shares core architectural features with other models in the family but is specifically configured as a full-duplex unit with a 500 kbps data rate capability and an independent VIO supply pin.

Replacement Considerations

ADM3068EBRZ (Same family, Full Duplex, 50 Mbps)

FAQ

Does the ADM3064EBRZ support PROFIBUS standards?

Yes, the device 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 on this transceiver?

The VIO pin serves as a separate logic supply input, allowing the digital interface to operate independently from the main power supply down to 1.62 V.

How does the device handle bus faults?

It incorporates a thermal shutdown circuit that detects significant temperature increases during fault conditions and forces the driver outputs into a high impedance state.
