SN74F299N3

Shift Registers Overview

The SN74F299N3 is an 8-bit universal shift/storage register from the Texas Instruments SN74F series. It features multiplexed I/O ports for full data handling within a single 20-pin package. The device operates on a supply voltage of 4.5 V to 5.5 V and supports four modes: Hold, Shift Right, Shift Left, and Load Data. It includes direct overriding clear functionality and three-state outputs suitable for bus lines. The component is designed for operation between 0°C and +70°C.

Shift Registers Feature Summary

• Supports four operational modes including hold, shift right, shift left, and synchronous parallel loading via function-select inputs.
• Features multiplexed I/O ports that allow bidirectional serial or parallel data transfer using a single set of terminals.
• Provides three-state outputs capable of driving bus lines directly while maintaining high-impedance states when disabled.

Shift Registers Applications

• Stacked or pushdown registers
• Buffer storage applications
• Accumulator registers

Shift Registers Procurement Notes

Verify the specific suffix 'N3' against official ordering information, as standard datasheets list 'SN74F299N' for the PDIP-20 tube package. Confirm RoHS compliance status and current production availability directly with Texas Instruments, as older F-series logic components may have limited stock or obsolescence notices.

Shift Registers Selection Notes

Select this component for designs requiring versatile data manipulation in a compact 20-pin form factor. Ensure the application utilizes the 4.5 V to 5.5 V supply range compatible with the SN74F bipolar logic family. Verify that the required operating temperature range aligns with the specified 0°C to +70°C commercial limits.

Shift Registers Part Context

This part belongs to the SN74F logic family, characterized by bipolar technology and high-speed performance relative to earlier standards. The SN74F299 specifically addresses needs for complex shifting and storage operations without requiring multiple discrete chips, consolidating eight bits of storage into one integrated circuit.

Shift Registers Replacement Considerations

Direct substitutes include the SN74F299DW (SOIC) or SN74F299NS (SOP). For pin-compatible alternatives with different electrical characteristics, consider the SN74ALS299 series.
