SN74ALS323DW

Shift Registers Overview

The SN74ALS323DW is an octal universal shift/storage register manufactured by Texas Instruments in the ALS-TTL logic family. It features multiplexed serial and parallel loading capabilities with tri-state outputs, housed in a 20-pin SOIC package. The device operates at a nominal supply voltage of 5 V, with a specified range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 19 ns, a low-level output current of 32 mA, and a high-level output current of -2.6 mA. It supports a maximum data rate of 125 Mbps and functions within a commercial temperature range of 0 °C to 70 °C.

Shift Registers Feature Summary

• Multiplexed serial and parallel input loading for flexible data entry
• Tri-state outputs allowing direct bus connection without external buffers
• Octal configuration providing eight independent storage elements

Shift Registers Applications

• High-speed data acquisition systems requiring parallel-to-serial conversion
• Buffering applications in digital communication interfaces
• General-purpose storage registers in microprocessor-based systems

Shift Registers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'DW' corresponds to the 20-pin SOIC package variant. Check for RoHS compliance status as indicated in official documentation. Ensure the operating environment remains within the specified commercial temperature limits to maintain performance reliability.

Shift Registers Selection Notes

Select this component when tri-state buffering and multiplexed loading are required in compact surface-mount designs. Compare against standard TTL variants for speed improvements offered by the ALS technology. Consider pin compatibility with legacy DIP packages if board space allows for alternative form factors. Evaluate power consumption requirements against other logic families for system efficiency.

Shift Registers Part Context

This part belongs to the Texas Instruments SN74ALS series, designed for advanced low-power Schottky applications. It serves as a successor to earlier 74Sxx devices, offering improved speed and lower power dissipation. The SN74ALS323DW specifically addresses needs for high-density digital storage in modern electronic assemblies.

Shift Registers Replacement Considerations

The SN74ALS323N is a verified PDIP equivalent from the same manufacturer. Cross-reference with SN74LS323 for functional similarity, noting potential differences in switching speed and power characteristics between LS and ALS technologies.
