Procurement Notes

Verify the specific suffix M2A against the official datasheet to ensure correct pinout and electrical characteristics. Confirm that the LCCC package dimensions match the target PCB footprint. Check for RoHS compliance status as military parts may have different environmental declarations. Ensure the supplier provides traceability documentation required for defense or critical infrastructure applications.

Selection Notes

Select this component when a high-speed, inverting octal buffer with three-state capability is required for harsh environments. It is suitable for designs needing TTL-compatible inputs and significant drive strength. Consider the 20-LCCC package constraints during layout. Evaluate thermal management requirements given the wide operating temperature range and power dissipation characteristics.

Part Context

This part belongs to the family of high-speed CMOS logic devices designed for demanding applications. It serves as a replacement or upgrade for older bipolar buffers, offering lower power consumption and higher speed. The military specification ensures performance stability under vibration and temperature extremes common in defense and space missions.

Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers that meet the same MIL-SPEC standards. Verify pin-to-pin compatibility if substituting with similar LCCC packages. Ensure the alternative device meets the 4.5 V to 5.5 V supply requirement and -55°C to +125°C temperature range.
