SN74AS374DWR

Flip Flops Overview

The SN74AS374DWR is an octal edge-triggered D-type flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 8.5 ns, a high-level output current of -3 mA, and a low-level output current of 24 mA. It supports TTL input levels and functions as a non-inverting logic circuit.

Flip Flops Feature Summary

• Contains eight independent edge-triggered D-type flip-flops for parallel data storage
• Provides three-state outputs to facilitate bus-oriented systems
• Operates with standard TTL input voltage levels
• Delivers high-speed performance with specified propagation delay characteristics

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Buffer registers in digital communication interfaces
• Data acquisition systems requiring temporary storage
• General-purpose memory elements in computing hardware

Flip Flops Procurement Notes

Verify the component authenticity by checking the manufacturer marking against official Texas Instruments documentation. Ensure the SOIC-20 package matches the specified pinout and physical dimensions. Confirm that the supply voltage requirements align with the system design before integration. Review the datasheet for any specific handling or storage conditions required for this logic family.

Flip Flops Selection Notes

Select this component when high-speed octal latching with three-state capability is required. It is suitable for applications needing TTL compatibility and moderate drive strength. Consider the power supply constraints and thermal management needs associated with the AS series logic family. Evaluate the package size and mounting style against the PCB layout requirements.

Flip Flops Part Context

This part belongs to the SN74AS series of advanced Schottky logic devices from Texas Instruments. It is functionally similar to other octal flip-flops like the SN74LS374 but offers faster switching speeds. The 'DW' suffix indicates the SOIC-20 surface-mount package, while the 'R' denotes reel packaging. It serves as a core building block for sequential logic designs in industrial and consumer electronics.

Flip Flops Replacement Considerations

Direct substitutes include the SN74AS374DR and SN74AS374N. Verify pin compatibility and electrical parameters before substitution. Cross-reference with SN74F374 or SN74HC374 only if speed and voltage levels are compatible.
