54FCT374CTLB

Overview

The IDT54FCT374CTLB is an octal D-type register featuring three-state outputs, manufactured using advanced dual metal CMOS technology. It belongs to the FCT series and provides eight D-type flip-flops with a buffered common clock and buffered three-state output control. The device operates within a temperature range of -55°C to 125°C and utilizes a 28-lead CQCC (LCC) package.

Feature Summary

• Octal D-type flip-flop configuration with non-inverting outputs
• Buffered common clock input for synchronized data transfer
• Three-state output control via active-low enable signal
• Compatible with TTL and CMOS logic levels

Applications

• High-performance bus interface buffering
• Wide data path storage applications
• Address latch circuits in microprocessor systems
• Parity generation and checking circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lead times and availability status prior to procurement. Ensure compliance with RoHS directives if required by project specifications. Validate packaging integrity upon receipt to prevent damage to ceramic LCC packages during handling.

Selection Notes

Select this component for applications requiring high-speed octal latching with low power consumption. Consider the military temperature range (-55°C to 125°C) for harsh environment deployments. Evaluate pin compatibility with existing PCB footprints when replacing legacy FAST logic devices. Ensure voltage levels match system requirements for reliable operation.

Part Context

This part is part of the IDT FCT (Fast CMOS) family, designed to replace older FAST logic families with improved speed and lower power. It offers performance comparable to or exceeding standard FAST specifications while maintaining CMOS power efficiency. The device is suitable for both commercial and military-grade applications requiring robust digital storage capabilities.
