• Memory interface circuits utilizing FCT logic levels
• General-purpose digital data routing applications

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer origin, as Harris Corporation's semiconductor assets were acquired by Renesas Electronics. Confirm that the specific part number corresponds to the original Harris production specifications rather than subsequent Renesas rebrands or equivalents. Ensure the package type matches the required 48-pin SSOP form factor for your PCB layout constraints.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems that require high-speed bidirectional data transfer using standard 5V logic levels. The integrated bus hold feature simplifies design by removing the requirement for external pull-up components. Consider the 48-pin SSOP package dimensions during mechanical layout planning to ensure adequate clearance and thermal management within the enclosure.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the FCT series of high-speed CMOS logic products originally developed by Harris Semiconductor. The series is characterized by compatibility with standard TTL logic levels while offering CMOS power advantages. The CD74FCT16245 variant specifically addresses bidirectional data flow requirements in complex digital architectures.

Buffers, Drivers, Receivers, Transceivers Replacement Considerations

Check for direct equivalents such as the CD74FCT16245DTMT which shares similar functional parameters but utilizes a TSSOP-48 package instead of SSOP. Verify pinout compatibility before substituting packages to avoid board redesign.
