Specialty Logic Procurement Notes

Verify the manufacturer designation as Harris Corporation, noting that this specific part number may also be associated with Renesas Electronics due to industry acquisitions. Confirm the package type is ceramic DIP-16 and ensure the temperature rating meets military specifications. Check RoHS compliance status as these legacy components are often non-compliant. Validate pinout compatibility if substituting into existing designs.

Specialty Logic Selection Notes

Select this component when designing systems requiring robust carry lookahead functionality under extreme thermal conditions. The ceramic package provides superior protection against moisture and mechanical stress compared to plastic variants. Ensure the design supports the required 5 V supply voltage and accommodates the through-hole footprint constraints inherent to the DIP-16 configuration.

Specialty Logic Part Context

This component belongs to the CD54 series of high-speed CMOS logic devices, characterized by military-grade reliability and hermetic sealing. The HCT suffix indicates compatibility with standard TTL input levels while maintaining CMOS power efficiency. The CD54 prefix distinguishes it from commercial CD74 equivalents by enforcing stricter manufacturing standards for aerospace and defense applications.
