Procurement Notes

Verify the manufacturer origin, as IDT assets are managed by Renesas Electronics. Confirm the specific package type matches system requirements. Check for RoHS compliance status if environmental regulations apply. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Review datasheet revisions for any functional updates.

Selection Notes

Select this component when an octal configuration with 3-state control is required for bus systems. Consider the Fast CMOS technology for applications needing moderate speed with lower power than older TTL equivalents. Verify that the 20-pin PLCC package fits the PCB layout constraints. Ensure the input/output voltage levels match the system logic standards.

Part Context

This part belongs to the 74FCT series of logic devices, which bridge the gap between standard TTL and high-speed CMOS technologies. The FCT series is known for its compatibility with TTL inputs while offering CMOS noise immunity and speed. This specific model provides a complete octal solution, reducing component count compared to using multiple single or dual buffers.

Replacement Considerations

Check for equivalent parts from other manufacturers such as Texas Instruments or ON Semiconductor that offer octal 3-state buffers in compatible packages. Verify pinout compatibility before substitution. Ensure electrical characteristics like output drive strength and propagation delay meet the original design specifications.
