CD74FCT16374TSM

Overview

The CD74FCT16374TSM is a 16-bit D-type flip-flop from the FCT/PCT-CMOS series, manufactured by Harris Corporation. It features independent control and bidirectional data handling capabilities within a single functional unit. The device utilizes a TSSOP-48 plastic package with a shrink pitch form factor. It operates on a nominal 5 V supply voltage and supports an operating temperature range of -40 °C to 85 °C. The component provides true output polarity with three-state output characteristics and includes internal series resistors for signal integrity.

Feature Summary

• Integrated 16-bit D-type flip-flop architecture for high-density data storage applications
• Three-state outputs with series resistors to manage bus loading and signal reflections
• Bus hold input functionality designed to eliminate the need for external pull-up resistors
• CMOS construction ensuring compatibility with standard logic families while maintaining low power consumption

Applications

• High-speed parallel data buffering in computer systems
• Interface circuits between microprocessors and peripheral devices
• Register files in digital signal processing architectures
• Memory address latching in embedded controller designs

Procurement Notes

Verify that the specific ordering suffix matches the required package type and pin configuration, as variations exist within the FCT family. Confirm RoHS compliance status if environmental regulations apply, noting that some Harris variants may not meet current standards. Ensure the supplier provides valid traceability documentation for the manufacturing date code. Cross-reference the JESD-30 code to confirm the physical package dimensions match the PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a 16-bit synchronous storage element is required with high-speed CMOS performance. The FCT series offers faster switching speeds compared to standard HCT logic, making it suitable for modern system buses. Consider the TSSOP-48 package for surface-mount assembly constraints. Evaluate the three-state output capability against system bus arbitration requirements. Verify that the 5 V supply voltage aligns with the target platform's power distribution network.

Part Context

This part belongs to the Harris CD74FCT163xx series of advanced fast CMOS logic devices. It is functionally related to other 16-bit storage elements like the CD74FCT16374TMT but differs in package type. The FCT line bridges the performance gap between standard TTL and high-speed CMOS technologies. Harris Corporation was a primary manufacturer before subsequent corporate acquisitions by Renesas Electronics.

Replacement Considerations

The CD74FCT16374TMT is a confirmed substitute part number offering identical logical functionality in a TSSOP-48 package. Verify pin-to-pin compatibility and electrical specifications before substitution. Other FCT series 16-bit flip-flops may require circuit redesign due to differing pinouts or control logic.
