SN74F299NSR

Shift Registers Overview

The SN74F299NSR is an octal universal shift and storage register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features a propagation delay of 11 ns. The device utilizes bipolar logic from the F series and provides tri-state outputs. It supports serial/parallel to serial/parallel counting sequences and includes asynchronous reset functionality. The component is housed in a 20-SOIC package with a wide operating temperature range from 0°C to +70°C.

Shift Registers Feature Summary

• Supports universal shift and storage operations with serial or parallel data loading capabilities
• Features tri-state outputs for effective bus line driving and isolation
• Includes asynchronous reset mechanism for immediate state clearing

Shift Registers Applications

• General-purpose digital data storage applications
• Serial-to-parallel and parallel-to-serial data conversion circuits
• Buffering and temporary data holding in digital systems

Shift Registers Procurement Notes

Verify the specific suffix 'NSR' against official manufacturer documentation to confirm the SOIC-20 surface mount package and reel packaging configuration. Ensure compatibility with standard 5V logic levels and check for RoHS compliance status in current datasheets before integration into designs requiring environmental certification.

Shift Registers Selection Notes

Select this component when an octal shift register with tri-state outputs and asynchronous reset is required. It is suitable for designs needing fast switching speeds provided by the F series logic family. Verify that the 20-pin SOIC footprint fits the board layout constraints and that the operating temperature range meets the system requirements.
