ADM3075EWYRZ-RL7

Drivers, Receivers, Transceivers Overview

The ADM3075EWYRZ-RL7 is a half-duplex RS-485 transceiver from Analog Devices, operating on a single 3.3 V supply. It supports data rates up to 500 kbps with slew rate limited drivers to minimize electromagnetic interference. The device features ±15 kV ESD protection on the A and B pins and includes true fail-safe receiver inputs that guarantee a logic high output when inputs are open or shorted. It operates within an extended temperature range of −40°C to +125°C and utilizes an 8-lead narrow SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• True fail-safe receiver inputs ensure a known logic high state when bus lines are open or shorted without requiring external bias resistors.
• Integrated hot-swap capability on DE and RE pins prevents erroneous data transfer during board insertion into powered backplanes.
• Slew rate limited driver outputs reduce electromagnetic emissions and signal reflections caused by improperly terminated transmission lines.

Drivers, Receivers, Transceivers Applications

• Power and energy metering systems
• Industrial control networks
• Lighting control infrastructure
• Telecommunications equipment
• Security system interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and reel specifications. Confirm RoHS compliance status and lead-free material declarations prior to integration. Ensure the selected variant matches the required duplex mode and temperature rating for the target application environment.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring half-duplex communication at speeds up to 500 kbps. The device is suitable for environments demanding robust ESD protection and fail-safe behavior. Consider the 8-lead package constraints and verify that the 3.3 V supply voltage aligns with the system power architecture.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM307xE family of low-power RS-485/RS-422 transceivers. The series offers various configurations including full-duplex options and higher speed variants up to 16 Mbps. All members share common features like thermal shutdown and short-circuit protection while differing in duplex mode and data rate capabilities.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3072E: Half-duplex, 250 kbps. ADM3078E: Half-duplex, 16 Mbps. ADM3074E: Full-duplex, 500 kbps. Verify pinout compatibility and electrical parameter alignment before substitution.
