74F280SC

Overview

The Fairchild Semiconductor 74F280SC is a 9-bit parity generator and checker integrated circuit belonging to the Fast (F) logic series. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum low-level output current of 20 mA. The device features a propagation delay of 10 ns and functions across an operating temperature range from 0 °C to +70 °C. It is housed in a 14-SOIC package with 14 terminals, designed for high-speed digital applications requiring reliable parity verification.

Feature Summary

• Performs 9-bit odd or even parity generation and checking functions
• Utilizes Fast (F) logic technology for high-speed signal processing
• Provides robust output drive capability suitable for standard logic loads

Applications

• Digital communication systems requiring data integrity verification
• Memory modules utilizing parity error detection
• High-speed computer bus architectures

Procurement Notes

Verify the manufacturer marking matches Fairchild Semiconductor specifications. Confirm the package type is 14-SOIC and the suffix indicates the correct variant. Ensure RoHS compliance documentation is available if required by your manufacturing standards. Cross-reference the part number against official distributor catalogs to confirm authenticity and avoid counterfeit components.

Selection Notes

Select this component when a 9-bit parity solution is required within the F-series speed class. It is appropriate for designs needing a single-chip parity generator/checker with standard TTL-compatible voltage levels. Consider the 14-SOIC footprint for PCB layout constraints. Verify that the 10 ns propagation delay meets the timing requirements of the target system clock speed.

Part Context

This component is part of the SN74F280 family of parity generators and checkers. It serves as a specialized logic IC for error detection in digital circuits. The device complements other F-series logic gates by providing dedicated parity functionality without requiring multiple discrete gates.

Replacement Considerations

The Texas Instruments SN74F280BNSR is a documented substitute offering identical 9-bit parity functionality and similar electrical characteristics. Both devices operate within the same voltage range and support SOIC packaging variants.
