Procurement Notes

Verify the specific suffix '118' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the AEC-Q100 Grade 1 classification aligns with target automotive application requirements. Cross-reference the 16-SOIC footprint dimensions with PCB layout constraints prior to finalizing component selection for production integration.

Selection Notes

Select this component when designing systems requiring eight-bit parallel data storage with tri-state output control. The HCT logic family ensures compatibility with TTL-level inputs while maintaining CMOS performance characteristics. Consider the 125°C maximum junction temperature rating for high-thermal environments typical in automotive electronics design workflows.

Part Context

This part belongs to the 74HCT series of automotive qualified logic devices produced by Nexperia. It complements other components like the 74HCT594 shift register and 74HC573 latch within the manufacturer's portfolio. The device adheres to JEDEC standards for electrical characteristics and mechanical dimensions, ensuring interoperability with standard digital logic circuits.

Replacement Considerations

The 74HC573D-Q100,118 serves as a functional substitute within the same product family. Verify pinout compatibility and electrical parameter alignment before implementing any cross-manufacturer replacements in existing designs.
