M74HC280RM13TR

Overview

The M74HC280RM13TR is a high-speed CMOS parity generator and checker manufactured by STMicroelectronics. It operates within a supply voltage range of 2V to 6V and features a single circuit configuration with nine inputs. The device utilizes Schmitt-trigger inputs for noise immunity and provides an active-low output indicating even parity. It is housed in a 14-pin SOIC surface-mount package and supports operation across an extended temperature range from -55°C to 125°C.

Feature Summary

• Implements parity generation and checking functions for data integrity verification
• Features Schmitt-trigger inputs to enhance noise rejection capabilities
• Provides active-low output signal corresponding to even parity status

Applications

• Data bus parity monitoring systems
• Communication interface error detection circuits
• Digital logic testing equipment

Procurement Notes

Verify the specific suffix RM13TR against official datasheets to confirm package type and reel specifications. Confirm RoHS compliance status as required by project standards. Check current lifecycle status, as availability may vary. Ensure operating conditions match the specified voltage and temperature ranges before integration.

Selection Notes

Select this component when a dedicated parity solution is required for multi-bit data streams. The HC series offers compatibility with standard logic families while providing improved speed over older variants. Verify that the nine-input capacity aligns with the system's data width requirements.

Part Context

This part belongs to the M74HC280 family of digital logic integrated circuits. It serves as a specialized function block within broader logic design architectures, distinct from general-purpose gates or flip-flops. The device complements other STMicroelectronics HC series components used in complex digital processing tasks.

Replacement Considerations

Direct substitutes include equivalent parity generators from other manufacturers such as SN74HC280 from Texas Instruments. Verify pinout compatibility and electrical characteristics before substitution.
