SN74ALS299DWR

Shift Registers Overview

The SN74ALS299DWR is an octal universal shift register manufactured by Texas Instruments. It features tri-state outputs and operates within a supply voltage range of 4.5 V to 5.5 V. The device utilizes the Advanced Low-power Schottky (ALS) logic series, providing a propagation delay of 12 ns. It is housed in a 20-SOIC package with surface-mount installation. The component supports serial-in/serial-out or parallel-in/parallel-out configurations.

Shift Registers Feature Summary

• Supports bidirectional shifting operations for data transfer applications
• Features tri-state outputs for bus-oriented system designs
• Integrates parallel load capability for direct data entry

Shift Registers Applications

• General-purpose data storage and manipulation circuits
• Serial-to-parallel conversion interfaces
• Parallel-to-serial conversion interfaces
• High-speed digital signal processing systems

Shift Registers Procurement Notes

Verify the specific suffix 'DWR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the ALS logic family specifications align with existing system timing constraints. Ensure compatibility with standard 5V logic levels before integration into final designs.

Shift Registers Selection Notes

Select this component when high-speed shifting capabilities are required alongside low power consumption characteristics inherent to the ALS series. Consider the 20-pin SOIC footprint for board space optimization. Evaluate the tri-state output feature against other logic families if bus isolation is a primary design requirement.

Shift Registers Part Context

This part belongs to the SN74ALS299 family of octal universal shift registers. It represents the Advanced Low-power Schottky technology variant, offering improved speed over standard LS logic while maintaining lower power dissipation than F-series counterparts. The DWR designation indicates the specific reel packaging configuration.
