RAA7881582GSP#AB0

Drivers, Receivers, Transceivers Overview

The RAA7881582GSP#AB0 is a half-duplex RS-485 interface integrated circuit manufactured by Renesas Electronics. It operates at a fixed supply voltage of 5 V and supports data transmission rates up to 10 Mb/s. The device is housed in an 8-lead Small Outline Integrated Circuit (SOIC) package with surface-mount technology. It functions within an industrial temperature range from -40 °C to +85 °C. The component provides high output drive capability, characterized by a typical differential output voltage of 3.1 V into a 54 Ω load. It includes fail-safe receiver outputs to ensure a high logic state when inputs are open or shorted.

Drivers, Receivers, Transceivers Feature Summary

• Robust electrostatic discharge protection rated at ±16.5 kV IEC 61000-4-2 without latch-up
• Ultra-low power consumption featuring 70 nA shutdown current and 550 μA driver-disabled supply current
• Supports high node density with 1/8 unit load configuration allowing up to 512 transceivers on the bus

Drivers, Receivers, Transceivers Applications

• Humanoid robot battery management systems requiring real-time power control
• Industrial process control networks and programmable logic controllers
• Motor controllers and encoders for automation equipment
• Telecom equipment utilizing RS-485 communication protocols

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix AB0 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure compliance with RoHS directives and humidity sensitivity levels before assembly. Cross-reference the SOIC-8 package dimensions with PCB footprint libraries to prevent mounting errors during surface-mount placement.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high noise immunity in electrically noisy environments due to its superior EFT and ESD ratings. Consider the 10 Mb/s data rate limit when designing high-speed serial communication links. Evaluate the 5 V supply constraint against system power rails, as the device does not support lower voltage operation. The half-duplex architecture suits bidirectional data exchange where simultaneous transmission and reception are not required.

Drivers, Receivers, Transceivers Part Context

This part belongs to the RAA78815 series of RS-485/RS-422 transceivers designed for robust industrial communication. The family includes various configurations such as full-duplex variants and different data rate options like 20 Mbps models. The RAA7881582 specifically denotes the half-duplex variant optimized for 10 Mb/s performance while maintaining low power consumption standards across the product line.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes within the same family include other RAA78815x variants with compatible pinouts. Verify that alternative parts match the 5 V supply requirement and SOIC-8 package type. Check if higher speed versions like the 20 Mbps models are functionally interchangeable regarding electrical specifications and thermal performance.
