SN74F299N

Shift Registers Overview

The SN74F299N is an 8-bit universal shift and storage register from the Texas Instruments SN74F logic family. It operates on a single circuit with bipolar logic technology, housed in a 20-pin PDIP package. The device supports serial/parallel to serial/parallel counting sequences and features asynchronous reset functionality. It provides three-state outputs for bus-driven applications. Electrical specifications include a propagation delay of 11 ns, operating within a supply voltage range of 4.5 V to 5.5 V, and functioning at temperatures between 0°C and +70°C.

Shift Registers Feature Summary

• Universal shift and storage capabilities supporting both serial and parallel data transfer modes
• Three-state outputs enabling direct connection to microprocessor buses without external buffers
• Asynchronous reset mechanism for immediate clearing of internal register states

Shift Registers Applications

• Data buffering in digital communication systems
• Parallel-to-serial conversion for transmission interfaces
• Serial-to-parallel conversion for receiving data streams

Shift Registers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure the selected variant matches the required package style and temperature rating for your design. Cross-reference ordering information with current datasheets to avoid discrepancies in manufacturing revisions or obsolete status.

Shift Registers Selection Notes

Select this component when high-speed shifting operations are required within standard TTL voltage levels. The SN74F series offers faster switching speeds compared to LS variants. Consider the 20-pin DIP package for through-hole prototyping or legacy board designs requiring manual assembly and replacement.
