IDT74FCT374ATSO

Overview

The IDT74FCT374ATSO is an octal D-type flip-flop manufactured by Renesas Electronics Corporation, belonging to the FCT logic series. It features a 20-pin SOIC package and operates within a supply voltage range of 4.5 V to 5.5 V. The component exhibits a maximum propagation delay of 7.2 ns and supports a maximum clock frequency of 10 MHz. Output drive capabilities include a low-level current of 48 mA and a high-level current of -15 mA. It functions across a temperature range from -40°C to +85°C.

Feature Summary

• Octal D-type flip-flop architecture providing eight independent data storage elements within a single integrated circuit.
• CMOS technology implementation ensuring compatibility with standard digital logic interfaces and power requirements.
• Three-state output configuration enabling direct bus connection without external buffering or level shifting.

Applications

• Parallel-to-serial data conversion circuits
• Buffered register implementations in digital systems
• I/O port interface management

Procurement Notes

Verify component authenticity through authorized channels due to potential availability of obsolete or refurbished units. Confirm RoHS compliance status as indicated in official documentation. Ensure packaging specifications match design requirements for surface-mount assembly processes. Validate thermal characteristics against system operating conditions before integration.

Selection Notes

Evaluate the 7.2 ns propagation delay against system timing constraints to ensure signal integrity. Assess the 48 mA sink current capability for driving load requirements on connected buses. Consider the 20-pin SOIC footprint for PCB layout compatibility. Verify that the 10 MHz maximum clock frequency aligns with the intended operational speed of the target application.

Part Context

This component belongs to the 74FCT374T family of octal D-type flip-flops. It shares functional similarities with other parts in the series but differs in package type and specific manufacturer branding. The IDT designation reflects its origin from Integrated Device Technology prior to acquisition by Renesas Electronics.

Replacement Considerations

Public confirmed substitute part numbers include 74FCT374ATSOG and IDT74FCT374ATSOG. These alternatives maintain identical logical functionality and pinout configurations suitable for direct replacement in existing designs.
