ADM3066ETRMZ-EP

Drivers, Receivers, Transceivers Overview

The ADM3066ETRMZ-EP is an enhanced product half-duplex RS-485 transceiver from Analog Devices, designed for harsh environments. It operates on a VCC supply of 3.0 V to 5.5 V and features a separate VIO logic supply ranging from 1.62 V to 5.5 V. The device supports data rates up to 50 Mbps with driver propagation delays of 9 ns typical and receiver delays of 35 ns typical. It provides robust ESD protection, including ±12 kV IEC contact discharge and DO-160 Section 25 compliance. The component is housed in an 8-lead MSOP package and functions within an extended industrial temperature range of −55°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• IEC 61000-4-2 ±12 kV contact discharge and DO-160 Section 25 air discharge ESD protection on bus pins without latch-up or damage.
• Flexible digital interface via the VIO pin allowing operation as low as 1.62 V for compatibility with various logic families.
• Full hot swap support ensuring glitch-free power-up and power-down sequences.
• Thermal shutdown circuit prevents excessive power dissipation during bus contention or output shorting conditions.

Drivers, Receivers, Transceivers Applications

• Industrial fieldbuses
• Process control systems
• Building automation networks
• PROFIBUS networks
• Motor control servo drives and encoders

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the tape and reel packaging format associated with the TRMZ designation. Confirm that the Enhanced Product (EP) status meets the required AQEC standard for defense and aerospace applications. Ensure the procurement channel provides access to qualification data and product change notifications as specified for this series.

Drivers, Receivers, Transceivers Selection Notes

Select the ADM3066ETRMZ-EP when a flexible VIO logic supply below the main VCC rail is required for interfacing with lower voltage controllers. This model is appropriate for designs needing high-speed 50 Mbps communication over multipoint bus lines. Consider the 8-lead MSOP package for space-constrained layouts requiring surface-mount assembly.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ADM3065E-EP/ADM3066E-EP/ADM3067E-EP family of enhanced product RS-485 transceivers. While the ADM3065E-EP lacks the VIO pin and the ADM3067E-EP offers full-duplex capability, the ADM3066E-EP specifically integrates the level translator for independent logic supply operation while maintaining half-duplex functionality.
