SN74LS280DRE4

Overview

The SN74LS280DRE4 is a 9-bit odd/even parity generator and checker manufactured by Texas Instruments. It belongs to the SN54LS280/SN74LS280 family and utilizes LS-TTL technology. The device operates with a supply voltage range of 4.75 V to 5.25 V and features a 14-pin SOIC package. It provides complementary outputs for odd and even parity verification.

Feature Summary

• Performs 9-bit odd and even parity generation and checking functions simultaneously.
• Provides complementary outputs indicating odd or even parity status.

Applications

• Data transmission systems requiring error detection
• Memory systems utilizing parity checking
• Digital communication interfaces

Procurement Notes

Verify the component matches the exact SN74LS280DRE4 designation, including the RE4 suffix which indicates lead-free and RoHS compliance. Confirm the package type is SOIC-14 and that the logic family corresponds to LS-TTL specifications. Ensure the operating temperature range aligns with commercial requirements.

Selection Notes

Select this component when a dedicated 9-bit parity solution within the LS-TTL family is required. Consider the 14-pin SOIC package for surface-mount applications. Verify compatibility with standard 5V logic levels and ensure the design accommodates the specific propagation delays associated with LS-series devices.

Part Context

This part is part of the broader SN54LS280/SN74LS280 series of parity generators/checkers. It shares functional characteristics with other members of the 74LS logic family but is distinguished by its specific 9-bit processing capability and SOIC packaging configuration.
