SN74F280BDR

Overview

The SN74F280BDR is a single-circuit, 9-bit parity generator and checker integrated circuit manufactured by Texas Instruments. It belongs to the SN74F logic series and is housed in a 14-pin SOIC package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from 0°C to +70°C. Key electrical specifications include a propagation delay of 10 ns, a high-level output current of -1 mA, and a low-level output current of 20 mA.

Feature Summary

• Performs 9-bit odd or even parity generation and checking functions
• Utilizes standard TTL input levels for compatibility
• Provides non-inverting outputs for direct signal interfacing

Applications

• Data transmission error detection systems
• Memory unit integrity verification
• Digital communication interface parity monitoring

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm any distinct manufacturing revisions or environmental compliance variations compared to standard variants. Ensure the SOIC-14 package dimensions align with PCB footprint requirements. Confirm RoHS status through the manufacturer's latest documentation before finalizing procurement orders.

Selection Notes

Select this component when a 9-bit parity solution is required within the SN74F family. Compare propagation delays and output drive capabilities against alternative logic families if higher speed or different voltage tolerances are needed. Verify that the 14-pin SOIC package fits the available board space and thermal constraints.

Part Context

This part is a member of the SN74F280 family, which specializes in parity functions. It shares functional similarities with other parity generators but is distinguished by its F-series speed characteristics and specific pinout configuration. It serves as a dedicated logic block for data validation tasks in digital circuits.

Replacement Considerations

SN74ALS280DR is a documented substitute offering similar parity functionality within the ALS series.
