LD8755A

Overview

The LD8755A is an I/O expander manufactured by Rochester Electronics, LLC. It is designed to expand the input and output capabilities of microcontrollers or other digital devices via serial communication interfaces. The component is available in bulk packaging and complies with RoHS standards for lead-free content. As a specialized interface IC, it facilitates system integration by providing additional general-purpose digital lines without requiring extensive hardware modifications.

Feature Summary

Provides expanded digital input and output ports for system connectivity
Supports serial communication protocols for efficient data transfer
Enables flexible integration with various microcontroller architectures

Applications

Embedded systems requiring additional GPIO pins
Industrial control panels needing interface expansion
Consumer electronics with limited microcontroller port availability

Procurement Notes

Verify the specific datasheet version and manufacturing lot details when sourcing from Rochester Electronics, LLC, as they supply components from original OEM specifications. Confirm that the package type and pinout match your design requirements. Ensure compliance with environmental regulations such as RoHS if applicable to your final product assembly process.

Selection Notes

Choose the LD8755A when existing microcontroller resources are insufficient for required peripheral connections. Evaluate the serial interface speed and voltage levels against your system bus characteristics. Consider the physical footprint and thermal performance relative to your enclosure constraints before finalizing the component selection.

Part Context

Rochester Electronics specializes in lifecycle management for obsolete and hard-to-find semiconductors. The LD8755A falls under their interface IC portfolio, offering continuity for designs originally utilizing this component. This ensures long-term supply stability for products that cannot easily migrate to newer generations of I/O expanders.
