Procurement Notes

Verify the specific suffix CTLB against official datasheets to confirm package type and speed grade. Ensure compliance with RoHS directives if required for the target application. Confirm lead-free status and environmental certifications prior to procurement.

Selection Notes

Select this component when an octal buffer with active-low enable is required. Consider the FCT series for superior speed compared to standard logic families. Evaluate pin compatibility with existing PCB layouts before substitution.

Part Context

This part belongs to the IDT FCT (Fast CMOS) family of logic devices. These components are engineered as high-performance replacements for older transistor-transistor logic (TTL) functions, offering faster switching speeds and lower power dissipation suitable for modern digital systems.

Replacement Considerations

Check for direct equivalents within the same FCT family. Verify pinout compatibility with alternative manufacturers' octal buffers. Ensure electrical characteristics such as drive strength and propagation delay meet system requirements.
