Procurement Notes

This component is officially obsolete and no longer manufactured by Texas Instruments. Verification of availability should focus on authorized distributors offering remaining stock or approved replacement parts. Ensure any substitute components maintain identical pinout compatibility and electrical specifications to prevent circuit redesign. Confirm RoHS compliance status for current inventory sources.

Selection Notes

Select this part only when legacy FCT series compatibility is required for existing designs. The dual 9-bit structure offers density advantages over single 8-bit alternatives. Verify that the 56-pin BSSOP package fits the target PCB layout constraints. Consider thermal performance within the specified industrial temperature range during integration planning.

Part Context

Part of the Texas Instruments CY74FCT logic family, designed for high-speed CMOS applications. This specific model integrates two independent 9-bit registers, optimizing space for wide data paths. It bridges older TTL-compatible logic levels with modern CMOS efficiency standards.
