Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the component matches the required HC logic family specifications and PDIP-20 package dimensions. Check RoHS compliance status and operating temperature ranges against project requirements. Ensure the supplier provides valid traceability documents and datasheet references corresponding to the exact part variant.

Selection Notes

Select this component when designing circuits requiring octal storage with tri-state capability within the HC logic family. Consider the 230 ns propagation delay and 7.8 mA drive strength for timing and load analysis. Verify compatibility with system voltage levels between 2 V and 6 V. Compare against SN74HC374N or CD74AC374E if different speed or temperature characteristics are needed.

Part Context
