SN74ALS29821DW

Flip Flops Overview

The SN74ALS29821DW is a 10-bit edge-triggered D-type flip-flop with 3-state outputs manufactured by Texas Instruments. It belongs to the ALS logic family and operates within a voltage range of 4.5 V to 5.5 V. The device features low static power consumption and high-speed performance, characterized by propagation delays typical for the ALS series. It is housed in a 24-pin SOIC package designed for surface-mount installation.

Flip Flops Feature Summary

• Features 3-state outputs specifically designed for driving highly capacitive or relatively long bus lines.
• Provides edge-triggered D-type latching functionality for data storage and transfer.
• Designed for low power dissipation while maintaining high-speed operation capabilities.

Flip Flops Applications

• Parallel data storage in digital systems
• Bus interface applications requiring high capacitive drive capability
• High-speed data transfer between microprocessors and peripheral devices

Flip Flops Procurement Notes

Verify the specific suffix 'DW' corresponds to the 24-pin SOIC package variant when sourcing. Confirm that the required operating temperature range aligns with commercial specifications, as military variants may carry different designators. Ensure compatibility with standard 5V logic levels before integration into existing circuit designs.

Flip Flops Selection Notes

Select this component for applications requiring 10-bit parallel data handling with high-speed switching characteristics. Consider the ALS family's balance between speed and power consumption relative to other logic families. Verify that the 3-state output configuration matches the system's bus architecture requirements for effective signal isolation.

Flip Flops Part Context

This component is part of Texas Instruments' extensive library of 74-series logic devices. It serves as a specialized solution for bus interface needs where multiple bits must be latched and driven simultaneously. The ALS designation indicates advanced low-power Schottky technology, offering improved performance over standard TTL equivalents.

Flip Flops Replacement Considerations

Direct substitutes include other 10-bit bus interface flip-flops from the same manufacturer family. Cross-reference pinouts and electrical characteristics carefully when considering alternative logic families such as BCT or AS series to ensure functional equivalence in high-speed bus environments.
