ADM3066EACPZ

Drivers, Receivers, Transceivers Overview

The ADM3066EACPZ is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc. It operates within a VCC supply range of 3.0 V to 5.5 V and features a separate VIO logic supply pin supporting 1.62 V to 5.5 V. The device supports data rates up to 50 Mbps with propagation delays of 9 ns (typical) for the driver and 20 ns (typical) for the receiver. It provides IEC 61000-4-2 ESD protection rated at ±12 kV contact discharge on bus pins. The component is housed in a 10-lead, 3 mm × 3 mm LFCSP package and functions across an extended temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• IEC 61000-4-2 Level 4 electrostatic discharge protection on bus pins without latch-up or damage
• Flexible digital interface via independent VIO logic supply pin
• Full hot swap support ensuring glitch-free power-up and power-down operations
• Receiver fail-safe mechanism maintaining logic high output during short-circuit, open circuit, or bus idle 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 against official documentation to confirm package type and temperature grade. Confirm that the VIO pin is utilized if low-voltage logic interfacing is required. Ensure PCB layout accounts for the exposed pad connection to ground for thermal management and electrical performance.

Drivers, Receivers, Transceivers Selection Notes

Select this model when half-duplex communication at 50 Mbps is required alongside robust ESD protection. The inclusion of the VIO pin distinguishes it from non-VIO variants like the ADM3065EACPZ. Verify compatibility with PROFIBUS standards if operating at VCC levels greater than or equal to 4.5 V.

Drivers, Receivers, Transceivers Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for high-speed multipoint bus transmission lines. It shares core specifications with other half-duplex models in the series but is distinguished by its specific package configuration and the availability of the VIO logic supply feature.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3065EARZ offers identical electrical performance but lacks the VIO pin and uses an SOIC-8 package. ADM3066EBRMZ provides the same functionality in a 10-lead MSOP package.
