SN74AS374NS

Flip Flops Overview

The SN74AS374NS is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 4.5V to 5.5V. The device utilizes Schottky technology for high-speed performance, with a maximum propagation delay of 11.5ns at 50pF load. It supports a clock frequency of 125MHz and provides output currents of 15mA (high) and 48mA (low). Packaged in a 20-SOIC surface-mount format, it functions as a non-inverting bus driver.

Flip Flops Feature Summary

• Octal D-type positive-edge triggered flip-flop architecture
• Three-state outputs for effective bus driving applications
• Schottky-clamped inputs and outputs for enhanced speed
• High current drive capability suitable for direct interface

Flip Flops Applications

• Parallel data storage and buffering
• Bus-oriented memory register implementations
• Clocked data latch circuits
• High-speed digital signal processing interfaces

Flip Flops Procurement Notes

Verify the specific suffix 'NS' corresponds to the SOIC-20 package variant when sourcing. Confirm RoHS compliance status as older AS series variants may differ from modern equivalents. Ensure the supplier provides official datasheets matching the Texas Instruments part number to avoid confusion with similar logic families. Cross-reference pinouts against the specific package drawing before integration.

Flip Flops Selection Notes

Select this component for designs requiring fast switching speeds and high current drive capabilities within standard 5V logic systems. The Schottky technology offers superior performance over standard LS or ALS series. Consider thermal dissipation requirements due to higher static current consumption compared to CMOS alternatives. Validate that the 20-SOIC package fits the available PCB footprint constraints.

Flip Flops Part Context

This part belongs to the Texas Instruments 74AS (Advanced Schottky) logic family, known for high speed. It serves as an octal flip-flop variant within the broader 74-series ecosystem. The SN74AS374NS specifically addresses applications needing rapid data latching with strong output drive, distinguishing it from lower-power HC or standard TTL counterparts.

Flip Flops Replacement Considerations

SN74ALS374NS: Offers similar functionality but with lower power consumption and slightly slower speed. SN74AS374N: Identical electrical characteristics but housed in a PDIP-20 through-hole package instead of surface mount.
