Procurement Notes

Verify the specific suffix G4 indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOIC-20 package dimensions match design constraints. Ensure the operating temperature range meets system environmental requirements. Cross-reference the datasheet revision to confirm electrical characteristics align with current design specifications.

Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for bus-based architectures. The FCT series offers compatibility with standard TTL inputs while providing CMOS performance levels. Consider the 20-SOIC package size for surface-mount assembly constraints. Evaluate the 10 ns propagation delay against system timing budgets to ensure signal integrity.

Part Context

This part belongs to the Texas Instruments 74FCT logic family, which combines the speed of ECL with the ease of use of CMOS technology. The CD74FCT374 variant specifically addresses the need for high-density octal registers in digital systems. It serves as a core building block for data storage and transfer in microprocessor-based designs.

Replacement Considerations

The CY74FCT374TQCT is a documented substitute offering similar functionality in a 20-SSOP package. Verify pinout compatibility and electrical parameters before substitution. Check if the alternative package requires PCB layout adjustments.
