LM8333GGR8X/NOPB

Controllers Overview

The LM8333GGR8X/NOPB is a mobile I/O companion device designed to support key-scan, I/O expansion, PWM, and ACCESS.bus host interface functions. Manufactured by Texas Instruments following the acquisition of National Semiconductor, this component integrates multiple peripheral control capabilities into a single package. It serves as a versatile interface solution for mobile applications requiring expanded input/output management and bus hosting capabilities.

Controllers Feature Summary

• Supports key-scan functionality for user input detection
• Provides general-purpose I/O expansion capabilities
• Includes pulse-width modulation (PWM) generation
• Acts as an ACCESS.bus host interface controller

Controllers Applications

• Mobile device peripheral control systems
• Key matrix scanning interfaces
• ACCESS.bus host controller implementations
• General-purpose I/O expansion in portable electronics

Controllers Procurement Notes

Verify the manufacturer designation carefully, as the part originates from National Semiconductor but is now produced under Texas Instruments. Confirm the exact suffix 'X/NOPB' matches your bill of materials, as variations like 'AXS/NOPB' exist with identical functional descriptions. Ensure compatibility with your system's voltage levels and interface requirements before procurement.

Controllers Selection Notes

Select this component when a single IC must handle key scanning, I/O expansion, PWM output, and ACCESS.bus hosting simultaneously. It is suitable for space-constrained mobile designs. Compare against dedicated I/O expanders if only one function is required, as this part offers integrated multi-functionality at the potential cost of higher complexity.

Controllers Part Context

This part belongs to the LM8333 family of mobile I/O companions. The 'NOPB' suffix typically indicates a lead-free and halogen-free compliant version. The 'GGR8' denotes the specific package type and pin configuration. Texas Instruments continues to support this line after acquiring National Semiconductor's analog portfolio.

Controllers Replacement Considerations

Direct substitutes include LM8333GGR8/NOPB and LM8333GGR8AXS/NOPB, which share identical functional descriptions. Verify pinout and electrical specifications match exactly before substitution. No other cross-model replacements are confirmed in public documentation.
