Procurement Notes
Verify the specific suffix 'NLV' indicates automotive grade qualification distinct from standard commercial variants. Confirm RoHS compliance status matches REACH requirements. Check datasheet revisions for any pinout or electrical parameter updates. Ensure packaging type matches system assembly needs. Validate supplier authenticity through authorized distribution channels.
Selection Notes
Select this component when a single OR gate is required in space-constrained designs. The wide voltage range allows compatibility with various power domains. Automotive qualification makes it suitable for harsh environments. Compare propagation delays against system timing requirements. Consider package size constraints during PCB layout planning.
Part Context
This part belongs to the 74HC series of high-speed CMOS logic devices. It provides standard OR functionality in a minimal footprint. The series is known for compatibility with TTL inputs while offering CMOS output levels. It serves as a fundamental building block for digital logic circuits requiring simple Boolean operations.
Replacement Considerations
Direct substitutes include MC74HC1G32DTT1G and 74HC1G32GV,125. Verify package compatibility and electrical specifications before substitution. Automotive variants may require specific qualification checks.
