Procurement Notes

Verify the specific M96 suffix against the manufacturer's official documentation to confirm pinout compatibility and electrical characteristics. Ensure the operating temperature range aligns with system requirements, as industrial variants may differ from commercial grades. Cross-reference the package outline drawing to validate mechanical fit for surface-mount assembly processes.

Selection Notes

Select this component when designing systems requiring octal storage with bus-compatible outputs. The FCT series offers faster switching speeds compared to standard HC logic, making it suitable for high-frequency applications. Consider the 5V-only supply constraint and ensure power delivery meets the peak current demands during switching transitions.

Part Context
