SN74S374N

Flip Flops Overview

The SN74S374N is an octal D-type positive edge-triggered flip-flop manufactured by Advanced Micro Devices. It integrates eight independent D-type flip-flops within a single 20-pin DIP package. The device features 3-state bus-driving outputs, allowing for efficient parallel access and loading. Control inputs are buffered to ensure signal integrity. Designed for TTL compatibility, this component operates at standard logic levels and supports high-speed data latching applications requiring multiple synchronized storage elements.

Flip Flops Feature Summary

• Integrates eight independent D-type flip-flops in a single package
• Features 3-state outputs for bus driving applications
• Positive edge triggering mechanism for precise timing control
• Buffered control inputs for improved signal handling

Flip Flops Applications

• Parallel data storage systems
• Bus interface circuits with tri-state capability
• High-speed digital logic designs requiring octal latching
• TTL-compatible system architectures

Flip Flops Procurement Notes

Verify the manufacturer marking on the component body to confirm Advanced Micro Devices origin, as Texas Instruments also produces equivalent parts. Check for the 'N' suffix indicating the plastic DIP package variant. Ensure the part number matches exactly to avoid confusion with similar octal flip-flops that may lack 3-state outputs or have different pin configurations. Request datasheets from authorized distributors to confirm current availability and authenticity.

Flip Flops Selection Notes

Select this component when an application requires eight synchronized D-type flip-flops with output enable capabilities. The 3-state outputs make it suitable for multiplexed bus structures where multiple devices share data lines. Consider the 20-DIP package for through-hole assembly requirements. Verify voltage compatibility with existing TTL logic levels before integration into the circuit design.

Flip Flops Part Context

This component belongs to the SN74S series of Schottky TTL logic devices, known for high-speed performance. The SN74S374 specifically addresses the need for octal storage with bus isolation. It complements other SN74S family members like shift registers and counters in complex digital systems. The part represents a standard solution for parallel data retention in legacy and industrial electronic designs.

Flip Flops Replacement Considerations

The SN54S374J serves as a military-grade equivalent with extended temperature range. Commercial alternatives include the SN74LS374, though it offers slower switching speeds. The SN74S374N is functionally compatible with other octal D-type flip-flops featuring 3-state outputs, provided pinouts match.
