Procurement Notes

Verify the manufacturer designation as Harris Corporation when sourcing this specific part number. Confirm the suffix MS2298 corresponds to the required packaging and tape-and-reel specifications. Ensure compatibility with the FCT logic family requirements for voltage and signal integrity. Cross-reference datasheet revisions to confirm pinout consistency with existing designs.

Selection Notes

Select this component for designs requiring octal width and registered storage within a single package. The FCT series offers speed advantages over standard LS logic while maintaining CMOS power characteristics. Verify that the system voltage aligns with the 5V nominal requirement. Consider the SOIC-24 footprint constraints during PCB layout planning.

Part Context

This device belongs to the FCT (Fast CMOS Technology) series, designed for high-speed digital applications. It serves as a bridge between microprocessors and peripheral devices, facilitating efficient data movement across system buses. The registered nature allows for synchronized data capture, reducing timing hazards in complex digital architectures.

Replacement Considerations

The CY74F652CTSOCT from Texas Instruments is a documented equivalent offering similar octal bus transceiver functionality. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement meets the same operating temperature and voltage specifications.
