MC74F299N

Shift Registers Overview

The MC74F299N is an 8-bit serial-in, parallel-out shift register from the onsemi F-series logic family. It features a single data input and eight parallel outputs, designed for digital circuit data storage and sequential transfer applications. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum low-level output current of 24 mA. It includes asynchronous clear and clock inputs for precise timing control. Packaged in a standard 16-pin DIP format, it functions reliably across an industrial temperature range of -40 °C to +85 °C.

Shift Registers Feature Summary

• Provides 8-bit serial-to-parallel data conversion capability
• Supports high-drive output currents for direct interface with loads
• Includes asynchronous clear functionality for immediate state reset

Shift Registers Applications

• Digital data processing systems requiring sequence shifting
• Timing control circuits for sequential operations
• Parallel data output expansion in microcontroller interfaces

Shift Registers Procurement Notes

Verify the specific suffix 'N' confirms the through-hole DIP package variant rather than surface-mount options. Confirm the manufacturer origin is onsemi or authorized successor entities like NXP, as ownership transfers may affect documentation availability. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Shift Registers Selection Notes

Select this component when an 8-bit serial shift register with parallel outputs is required in the F-series logic family. It is suitable for designs needing robust drive strength at 5V logic levels. Consider alternative series such as HC or HCT if lower power consumption or CMOS compatibility with 3.3V systems is necessary instead of the higher speed and drive of the F-series.

Shift Registers Part Context

This part belongs to the onsemi F-series of high-speed silicon-gate logic devices. The F-series is characterized by fast propagation delays and strong output drive capabilities compared to standard TTL or later CMOS families. Shift registers in this family are commonly used for temporary data storage and time-delay generation in digital electronics.

Shift Registers Replacement Considerations

Check for MC74F299N equivalents from other manufacturers such as NXP or Texas Instruments. Verify pinout compatibility and electrical characteristics before substitution. Note that some variants may have different packaging or voltage tolerances.
