Procurement Notes

Verify the specific revision level and date code upon order confirmation. Confirm compliance with project-specific material restrictions, as this part is leaded and non-RoHS. Ensure the ceramic DIP-14 package matches the target footprint. Request test data if required for critical reliability assessments. Rochester Electronics components may carry dual markings; verify the part number against the official datasheet specifications before implementation.

Selection Notes

Select this component when a quad bus driver with three-state outputs is required for high-reliability applications. The ceramic package offers superior thermal and mechanical stability compared to plastic variants. Consider the operating temperature range of -55 °C to 125 °C for harsh environment suitability. Verify that the true output polarity aligns with the system logic requirements. Ensure the leaded construction meets all regulatory constraints for the intended deployment.

Part Context

Rochester Electronics specializes in sourcing and manufacturing obsolete and hard-to-find semiconductors. This component is part of their extensive inventory of legacy logic devices. The company provides licensed manufacturing services and quality assurance for discontinued parts.
