Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor assets are now managed by onsemi. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the SOIC-20 package dimensions match your PCB footprint design constraints before finalizing procurement orders.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when high drive current is required for bus lines or memory interfaces. The wide supply voltage range allows compatibility with various logic families. Consider the extended temperature rating for harsh environment applications where standard commercial grade parts may fail.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74C series of CMOS logic devices, which offers higher speed and drive capability compared to older 74LS TTL equivalents while maintaining CMOS power efficiency. The MM74C240 variant specifically provides octal buffering with tri-state functionality for system bus management.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Equivalent parts include the MM74HC240WMX for HC series performance or the SN74C240N for pin-compatible alternatives. Verify electrical characteristics such as propagation delay and output current ratings against the original specification sheet before substitution.
