Procurement Notes
Verify the complete ordering code including the suffix ,118 to ensure correct tape-and-reel packaging. Confirm that the specific variant matches the required AEC-Q100 Grade 1 automotive qualification level. Check the datasheet for pinout compatibility with existing PCB footprints. Ensure supply voltage requirements align with the target system design before procurement.
Selection Notes
Select this component when designing for automotive environments requiring robust noise immunity and wide voltage tolerance. The HC series offers high-speed performance suitable for complex digital interfaces. Consider the 20-SOIC package dimensions for space-constrained layouts. Verify thermal management needs against the specified operating temperature range.
Part Context
This part is an automotive-qualified version of the standard 74HC574 octal flip-flop. It integrates eight independent D-type latches into a single integrated circuit. The design emphasizes reliability and stability for harsh operational conditions found in modern vehicles. It serves as a fundamental building block for sequential logic circuits.
Replacement Considerations
Direct substitutes include other AEC-Q100 qualified octal D-type flip-flops from manufacturers such as Texas Instruments or STMicroelectronics. Cross-reference pinouts and electrical specifications carefully. Non-automotive grade equivalents lack the required environmental testing certification.
