SN74AS374N-J

Flip Flops Overview

The SN74AS374N-J is a Schottky-clamped octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features eight independent D-type flip-flops with tri-state outputs, designed for high-speed digital applications within the 74AS logic family. The component operates on a single 5V supply voltage ranging from 4.5V to 5.5V. It utilizes a 20-pin dual in-line package (PDIP) suitable for through-hole mounting. The device supports a maximum clock frequency of 125 MHz and includes an active-low master reset input that overrides data inputs.

Flip Flops Feature Summary

• Integrates eight independent D-type edge-triggered flip-flops with tri-state outputs for high-speed data storage and bus interfacing.
• Incorporates Schottky barrier diodes to prevent saturation, significantly reducing storage time and enhancing switching speed compared to standard logic families.
• Features an active-low master reset input that forces all outputs to a low state regardless of clock or data conditions.

Flip Flops Applications

• High-speed register implementations in digital systems
• Bus-oriented memory registers requiring tri-state isolation
• Parallel-to-serial conversion circuits
• Data acquisition systems utilizing fast sampling rates

Flip Flops Procurement Notes

Verify the specific suffix 'J' against the manufacturer's official documentation to confirm military-grade qualification requirements. Ensure the procurement channel provides valid traceability certificates if aerospace or defense specifications are mandated. Confirm RoHS compliance status as historical variants may differ from current production standards.

Flip Flops Selection Notes

Select this component when system design demands propagation delays lower than those offered by standard 74F series devices. The tri-state output capability allows direct connection to shared data buses without external buffering. Consider the PDIP-20 package constraints regarding board space and thermal dissipation relative to surface-mount alternatives.

Flip Flops Part Context

This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for superior speed-power product characteristics. It serves as a high-performance alternative to the SN74S374, offering faster switching times while maintaining compatibility with standard TTL logic levels. The device is part of a broader ecosystem of Schottky-clamped logic components designed for demanding digital environments.

Flip Flops Replacement Considerations

SN74AS374NS: Surface mount SOIC variant with identical electrical characteristics. SN74S374: Standard Schottky equivalent with slightly slower performance metrics. SN74LS374: Low-power Schottky alternative with significantly reduced speed capabilities.
