Procurement Notes

Verify the specific suffix YRM13TR against official STMicroelectronics documentation to confirm tape-and-reel packaging and automotive qualification status. Ensure the ordering code matches the exact pinout and electrical characteristics required for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance and environmental declarations prior to procurement.

Selection Notes

Select this component when a dedicated hardware solution for parity calculation is required in HC logic families. Consider the 14-pin SOIC package constraints and the 2V to 6V operating voltage window. Evaluate the 80μs propagation delay against system timing requirements. Verify that the input current specifications align with the driving stage capabilities of the upstream logic gates.

Part Context

This part belongs to the M74HC14 series family of high-speed CMOS logic devices produced by STMicroelectronics. The M74HC280 specifically addresses parity generation and checking tasks within digital logic applications. It utilizes silicon gate C2MOS technology to achieve performance compatible with standard 74 series logic while offering improved power dissipation characteristics typical of modern CMOS processes.

Replacement Considerations

Check for direct pin-compatible alternatives within the M74HC280 product line from other manufacturers. Verify electrical parameter equivalence, particularly regarding propagation delay and output drive strength. Ensure the replacement supports the same 14-pin SOIC package and operating temperature range.
