Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as National Semiconductor or its successor Microchip Technology when sourcing this component. Confirm the package type is 20-PDIP and the logic series is 74BCT. Ensure the datasheet specifies tri-state functionality and inverted outputs to match design requirements. Cross-reference part numbers carefully due to potential corporate acquisitions affecting branding.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require dual four-bit inverting buffers with tri-state control. It is suitable for applications needing compatibility with 5V logic levels and moderate speed performance. Consider the 20-PDIP package if through-hole assembly is required. Evaluate propagation delay specifications against system timing constraints before finalizing the selection.

Buffers, Drivers, Receivers, Transceivers Part Context

This component belongs to the 74BCT family, which bridges Bipolar TTL speed with CMOS power efficiency. National Semiconductor was acquired by Texas Instruments, and later its semiconductor assets were transferred to Microchip Technology. The 74BCT2240PC represents a legacy part number from this lineage, maintaining functional compatibility with standard 74-series logic interfaces.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for equivalents from Microchip Technology, such as the MBT2240 series, which may carry updated part numbers. Verify pinout compatibility and electrical characteristics against current datasheets from the new manufacturer. Ensure the replacement maintains the dual four-bit inverting buffer architecture and tri-state output functionality.
