Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer, indicating that production has ceased and future availability is not guaranteed. Verification of specific lot dates and final stock levels through authorized distributors is essential before integration into new designs. Engineers should confirm RoHS compliance status, which may differ from standard industry expectations for legacy parts, and review any Product Change Notices related to packaging or labeling updates prior to procurement.

Selection Notes

Select this part when a single-chip solution for eight-bit parallel data storage with high-drive capability is required. The wide operating temperature range makes it suitable for industrial applications where standard commercial grade components are insufficient. Ensure the system design accommodates the 20-CDIP through-hole package dimensions and verify that the 4.5V to 5.5V supply rail aligns with existing board power distribution.

Part Context

The 74FCT574ATDB belongs to the FCT (Fast CMOS TTL-compatible) logic family, designed for high-speed digital systems requiring compatibility with TTL input levels while utilizing CMOS technology for lower power consumption. This specific variant represents the industrial temperature grade version of the octal D-latch, offering enhanced reliability compared to commercial equivalents.
