CD74FCT373CTQM

Latches Overview

The CD74FCT373CTQM is an octal transparent latch manufactured by Harris Corporation, belonging to the FCT logic series. It features true TTL input and output compatibility with low leakage currents of 1µA maximum. The device operates at CMOS power levels and includes three-state outputs for bus driving applications. It is housed in a 20-SSOP package and supports surface mount installation.

Latches Feature Summary

• Octal transparent latch architecture with three-state outputs
• True TTL input and output compatibility
• Low input and output leakage current
• CMOS power consumption levels

Latches Applications

• Data synchronization circuits
• Mechanical switch debouncing
• Temporary data registers

Latches Procurement Notes

Verify component authenticity through authorized distributors or Harris Corporation channels. Confirm RoHS compliance status as historical documentation may vary. Check for end-of-life notifications or product change notices from Renesas Electronics, which acquired Harris semiconductor assets. Ensure package integrity matches the 20-SSOP specification before integration.

Latches Selection Notes

Select this component when true TTL compatibility is required alongside CMOS power efficiency. The FCT series offers faster switching speeds compared to standard HC/HCT logic families. Verify that the 20-SSOP package fits the target PCB footprint. Consider the three-state output capability for shared bus architectures requiring high impedance states.

Latches Part Context

This part belongs to the Harris CD74FCT373T family of octal latches. Harris Corporation was a major semiconductor manufacturer before its acquisition by Renesas Electronics. The FCT series represents Fast CMOS technology designed to bridge the performance gap between standard CMOS and TTL logic families while maintaining low power consumption.

Latches Replacement Considerations

IDT74FCT373CTPYG is a documented substitute part number for this component. Verify pinout and electrical specifications match before substitution. Renesas Electronics now manages the legacy Harris logic portfolio.
