54ACTQ32JRQMLV

Overview

The 54ACTQ32JRQMLV is a quad 2-input OR gate manufactured by National Semiconductor, part of the ACT series. It features four independent logic channels within a single package. The device utilizes CMOS technology and is housed in a 14-pin Ceramic Dual In-Line Package (CERDIP). This component is designed for high-speed digital applications requiring reliable logical OR operations across multiple inputs.

Feature Summary

• Quad configuration providing four independent 2-input OR logic functions
• ACT series architecture optimized for high-speed switching performance
• CMOS construction ensuring low power consumption relative to output drive capability
• Ceramic Dual In-Line Package (CERDIP) offering robust environmental sealing

Applications

• Military aerospace digital logic systems
• High-reliability communication equipment
• Industrial control logic circuits

Procurement Notes

Verify the specific suffix JRQMLV confirms military-grade qualification and ceramic packaging when sourcing. Ensure the supplier provides traceability documentation consistent with National Semiconductor or Texas Instruments standards for this specific part number. Confirm the package type matches the required 14-CERDIP specification for your assembly process.

Selection Notes

Select this component when a quad OR gate is required in a radiation-hardened or high-temperature environment. The CERDIP package is suitable for hermetic sealing needs. Compare against standard plastic DIP variants if environmental protection is not critical, noting that the QMLV suffix indicates specific reliability screening beyond commercial grades.

Part Context

This part belongs to the 54ACT family, which bridges the performance gap between older TTL and standard CMOS technologies. The 'Q' typically denotes qualified/military grade, while 'MLV' often refers to specific lead-free or military lot variations. It serves as a direct replacement for older 54LS32 equivalents in high-speed designs requiring lower power.

Replacement Considerations

Direct substitutes include other 54ACT32 variants in CERDIP packages from National Semiconductor or Texas Instruments. Verify pin compatibility and voltage levels. Generic 74ACT32 plastic packages are not equivalent due to package differences and lack of military qualification.
