ADM3071EYRZ

Drivers, Receivers, Transceivers Overview

The ADM3071EYRZ is a full-duplex RS-485/RS-422 transceiver from Analog Devices, operating on a single 3.3 V supply. It supports data rates up to 250 kbps with slew rate limited drivers to minimize EMI. The device features ±15 kV ESD protection on bus pins and true fail-safe receiver inputs that guarantee a logic high output when inputs are open or shorted. Packaged in an 8-lead narrow SOIC, it lacks shutdown functionality but includes thermal shutdown and short-circuit protection for robust operation across the -40°C to +125°C temperature range.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication capability with independent driver and receiver paths
• Integrated ±15 kV ESD protection on A, B, Y, and Z pins
• True fail-safe receiver design ensuring known logic state during idle conditions
• Slew rate limited outputs to reduce electromagnetic interference

Drivers, Receivers, Transceivers Applications

• Power and energy metering systems
• Industrial control networks
• Lighting system management
• Telecommunications equipment
• Security and instrumentation devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'Y' indicates the extended industrial temperature range of -40°C to +125°C rather than the standard commercial range. Confirm package type matches the 8-lead narrow SOIC requirement. Check RoHS compliance status as indicated in official documentation. Ensure ordering codes align with current Analog Devices manufacturing revisions.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex signaling without the need for low-power shutdown modes. It is suitable for environments where hot-swap insertion is not required, as this feature is absent in the ADM3071E variant. Consider the 8-lead package constraint against pin count requirements for enable signals compared to 14-lead alternatives.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ADM307xE family of 3.3 V transceivers designed for multipoint bus transmission lines. Unlike the ADM3070E which uses a 14-lead package with shutdown capabilities, the ADM3071E utilizes an 8-lead configuration optimized for space-constrained designs while maintaining full-duplex performance and high ESD tolerance standards.

Drivers, Receivers, Transceivers Replacement Considerations

ADM3070EYRZ offers identical electrical performance but includes shutdown functionality and uses a 14-lead package. ADM3074EYRZ provides similar 8-lead packaging but operates at 500 kbps. Verify pin compatibility and functional differences regarding enable controls before substitution.
