• Military-grade electronic equipment requiring radiation tolerance

Procurement Notes

Verify the specific suffix TLB against official datasheets to confirm package type and speed grade. Confirm RoHS compliance status as legacy military variants may differ from commercial equivalents. Check manufacturer notices for obsolescence or lifecycle changes before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring octal storage with tri-state control and TTL compatibility. Ensure the operating environment matches the specified temperature range. Verify that the required speed grade meets the system timing constraints compared to other available FCT series options.

Part Context

This part belongs to the IDT FCT (Fast CMOS) family of logic devices. The family is characterized by high-speed operation comparable to LS-TTL but with CMOS power efficiency. The 54 prefix indicates military-grade qualification, distinguishing it from the commercial 74 series counterparts within the same functional lineage.

Replacement Considerations

Cross-reference with IDT 74FCT574TLB for commercial grade equivalents. Verify pinout compatibility with Texas Instruments CY74FCT574 variants if substituting manufacturers.
