ADM3063EARZ

Overview

The ADM3063EARZ 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 data rates up to 500 kbps. The device provides IEC 61000-4-2 electrostatic discharge protection withstanding ±12 kV contact and air discharges without latch-up or damage. It features a 1/4 unit load input impedance, allowing connection of up to 128 transceivers on the bus. The component includes receiver fail-safe capabilities for short-circuit, open circuit, and bus idle conditions, along with thermal shutdown protection. It is housed in a 14-lead narrow-body SOIC package.

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature grade. Confirm that the selected variant matches the required duplex mode and data rate specifications for the target application environment.

Selection Notes

Select this model when full-duplex communication at 500 kbps is required alongside robust ESD protection. Ensure the system design accommodates the 14-lead SOIC footprint and verify that the logic interface requirements align with the fixed VIO configuration available in this specific part number.

Part Context

This component belongs to the ADM306xE family of RS-485 transceivers designed for harsh industrial environments. The series offers various speed grades and duplex options, with the ADM3063E specifically providing full-duplex capability at lower speeds optimized for long cable runs.
