54FCT374ATDB

Overview

The IDT54FCT374ATDB is an octal D-type register manufactured by Integrated Device Technology. It utilizes advanced dual metal CMOS technology to provide high-speed data storage capabilities. The device features eight non-inverting outputs with three-state control, allowing for efficient bus-oriented architectures. It operates within a supply voltage range of 4.5V to 5.5V and supports a wide industrial temperature range from -55°C to +125°C. The component is housed in a 20-lead Ceramic Dual In-Line Package (CDIP).

Feature Summary

• Octal D-type flip-flops with buffered common clock input.
• Three-state output control for bus-driven applications.
• Non-inverting outputs relative to the data inputs.
• Edge-triggered master/slave architecture.

Applications

• Bus-oriented memory mapping systems.
• High-performance register designs.
• Data acquisition and storage circuits.

Procurement Notes

Verify the specific manufacturer source, as this part number may be associated with Renesas Electronics following industry acquisitions. Confirm RoHS compliance status, as historical records indicate non-compliance for certain variants. Check current lifecycle status, as production may be discontinued or subject to obsolescence notices. Ensure the ceramic package type matches the design requirements for thermal and mechanical stability.

Selection Notes

Select this component when designing systems requiring fast CMOS logic with high drive capability. The 48mA low-level output current supports direct driving of multiple loads. Consider the CDIP package for through-hole mounting needs. Verify that the operating temperature range meets the environmental constraints of the target application. Compare propagation delay specifications against system timing requirements.

Part Context

This component belongs to the FCT (FAST CMOS) logic family, designed to offer performance comparable to TTL but with CMOS power efficiency. The 54FCT374 variant specifically provides octal registration functionality. It is often used in conjunction with other FCT buffers and transceivers to create complex digital logic systems requiring reliable data latching and bus management.
