RAA7881732GSU#AB0

Drivers, Receivers, Transceivers Overview

The RAA7881732GSU#AB0 is a full-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply voltage and supports data rates up to 500kbps. The device features a low-power shutdown mode with an operating supply current of 510µA. It provides robust protection against electrostatic discharge (ESD) and electrical fast transients (EFT), compliant with IEC 61000 standards. The component is housed in a 10-lead MSOP package and is rated for an operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• High ESD and EFT immunity for reliable communication in noisy environments
• Full fail-safe receiver ensures a high logic state when inputs are open or shorted
• Low-power shutdown capability reduces energy consumption during idle periods

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation and HVAC networks
• Smart metering infrastructure

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix #AB0 against the manufacturer's official documentation to confirm packaging type and environmental compliance status. Ensure the requested quantity aligns with standard factory packing configurations. Confirm lead times directly with authorized distributors as availability fluctuates based on production schedules.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 communication at moderate speeds with enhanced transient protection. Compare pinout compatibility and thermal performance against existing designs. Verify that the 3.3V supply voltage matches the system power architecture and that the MSOP package fits the available PCB footprint constraints.

Drivers, Receivers, Transceivers Part Context

This part belongs to the RAA78817x series of 3.3V RS-485/RS-422 transceivers designed for industrial interfaces. The series emphasizes high output drive capabilities combined with superior EFT and ESD protection, addressing common reliability issues in harsh electromagnetic environments typical of industrial and commercial installations.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same RAA78817 family or comparable RS-485 transceivers from other manufacturers. Ensure substitute parts meet the same EFT/ESD immunity levels and operate within the specified -40°C to +85°C temperature range without requiring circuit modifications.
