CD74FCT16374ATMT

Overview

The CD74FCT16374ATMT is a 16-bit D-type flip-flop manufactured by Harris Corporation, belonging to the FCT/PCT-CMOS logic family. It features a TSSOP-48 plastic package with a thin profile and shrink pitch. The device operates on a nominal 5V supply voltage, supporting a range of 4.5V to 5.5V. It provides 3-state outputs with a maximum output current of 0.064A and a load capacitance of 50pF. The propagation delay at nominal supply is 10ns. Operating temperatures range from -40°C to 85°C.

Feature Summary

• Contains two independent 8-bit D-type flip-flop elements for parallel data storage.
• Features positive edge triggering for precise timing control.
• Includes bus hold inputs to eliminate the need for external pull-up resistors.
• Provides 3-state outputs with series resistance for reliable bus interfacing.

Applications

• Parallel data latching in high-speed digital systems
• Interface buffering between microprocessors and peripheral devices
• Register file implementation in embedded controllers

Procurement Notes

Verify the manufacturer designation, as Renesas Electronics also lists this part number in public databases. Confirm the specific suffix 'ATMT' matches the required tape-and-reel packaging and temperature grade. Ensure the component meets the required RoHS compliance status, as original Harris versions may be non-compliant. Cross-reference the datasheet version to confirm pinout compatibility with your PCB layout.

Selection Notes

Select this component when a 16-bit parallel register with tri-state outputs is required. The FCT series offers CMOS compatibility with TTL-level input thresholds. Consider the 10ns propagation delay for system timing budgets. The TSSOP-48 package is suitable for surface-mount assembly. Verify that the bidirectional or unidirectional data flow requirements match the single-direction nature of this D-type flip-flop.

Part Context

This component is part of the Harris FCT (Fast CMOS Technology) logic family, designed for high-speed applications. It serves as a fundamental building block for sequential logic circuits. The device integrates well with other FCT-series buffers and transceivers. Its 48-pin form factor allows for dense circuit board layouts in complex digital designs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Check for direct pin-to-pin replacements within the same FCT series or updated Renesas equivalents if sourcing from current manufacturers.
