CD74FCT16374CTMT

Overview

The CD74FCT16374CTMT is a 16-bit D-type flip-flop from the FCT series, manufactured by Harris Corporation. It features a 48-pin TSSOP package and operates within a voltage range of 4.5V to 5.5V. The device provides registered bus transceiver functionality with three-state outputs and a propagation delay of 10 ns at nominal supply. It supports an operating temperature range from -40°C to 85°C.

Feature Summary

• Provides 16-bit positive edge-triggered D-type registration
• Features three-state outputs for bus driving applications
• Incorporates bus hold inputs to eliminate external pull-up resistors

Applications

• High-speed data register storage
• Bus interface circuitry
• Parallel-to-serial conversion systems

Procurement Notes

Verify the manufacturer designation as Harris Corporation or its successor entities such as Renesas Electronics, depending on production era. Confirm the package type is 48-TFSOP (TSSOP) with a width of 0.240 inches. Ensure compliance with RoHS directives if required, noting that some listings indicate non-compliance status. Cross-reference datasheets for specific suffix variations like 'TMT' versus 'CTMT' to confirm pinout and electrical characteristics match the design requirements.

Selection Notes

Select this component for applications requiring 16-bit parallel data latching with high-speed performance. The FCT series offers compatibility with standard CMOS logic levels while providing enhanced drive capabilities. Consider the 48-pin thin profile package for space-constrained designs. Verify that the 10 ns propagation delay meets the system timing constraints. Ensure the operating temperature range aligns with the environmental conditions of the target application.

Part Context

This part belongs to the FCT (Fast CMOS) family of logic devices, designed for high-speed digital applications. It serves as a registered bus driver, combining flip-flop functionality with bus transceiver capabilities. The device is part of a broader portfolio of Harris/Renesas logic ICs aimed at improving system performance in computing and communication equipment.

Replacement Considerations

The CD74FCT16374TMT is a documented variant within the same product line. Verify pin compatibility and electrical specifications before substitution. Other FCT-series 16-bit registers may serve as functional alternatives if package and timing parameters align.
