• Integrates two independent 3-bit buffer elements within a single package
• Supports direct connection to microprocessor buses via three-state outputs

Applications

• Microprocessor address and data bus buffering
• Clock distribution networks requiring signal isolation
• Digital logic interface circuits needing tri-state control

Procurement Notes

Verify the manufacturer part number 40097BDC against official National Semiconductor or Microchip documentation to confirm specifications. Ensure the 16-CDIP package type matches your board design requirements. Check RoHS compliance status if required by your manufacturing standards. Confirm that the tri-state functionality aligns with your system's bus architecture before procurement.

Selection Notes

Select this component when a hex buffer with tri-state capability is required for bus isolation. The 16-CDIP package is suitable for through-hole assembly processes. Consider the non-inverting logic function and the specific pinout configuration of the 40097BDC compared to alternative buffer families. Ensure voltage levels and drive current requirements are met by the datasheet specifications.
