Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to ensure correct package and temperature grade specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or onsemi sales representatives prior to procurement planning.

Selection Notes

Select this component when designing systems requiring dedicated capacitance-to-digital conversion for touch inputs. Ensure the application environment matches the specified operating temperature range and supply voltage requirements. Verify interface compatibility with the host microcontroller before finalizing the bill of materials.

Part Context

This part belongs to the LC717A series of capacitance-digital converters from onsemi. It shares functional similarities with other members like the LC717A00AR and LC717A10PJ but differs in specific pinout configurations and channel counts. The NH suffix typically denotes specific packaging or environmental compliance variations within the product line.

Replacement Considerations

Potential substitutes include the LC717A00AR and LC717A10PJ from the same manufacturer family. Verify pin compatibility and software register maps before substitution. Cross-reference with LC717A30UJ if higher channel counts are required.
