54ACTQ32WRQMLV

Overview

The 54ACTQ32WRQMLV is a quad 2-input OR gate from the Quiet Series ACT logic family, manufactured by National Semiconductor. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -55°C to 125°C. The device is housed in a 14-CFlatpack surface-mount package. As part of the QML (Military) qualified line, it is designed for high-reliability applications requiring radiation tolerance.

Feature Summary

• Radiation-hardened design suitable for harsh environments
• High-speed CMOS technology with low power consumption
• Extended industrial temperature range capability

Applications

• Military aerospace systems
• Satellite communication equipment
• Spacecraft data processing units

Procurement Notes

Verify the specific QML qualification level and lot traceability documentation upon receipt. Confirm that the 14-CFlatpack package matches the mechanical constraints of the target assembly. Ensure storage conditions comply with moisture sensitivity levels for leaded flatpack components to prevent damage during soldering processes.

Selection Notes

Select this component when radiation hardness and wide temperature operation are critical requirements. Compare pin compatibility with standard 54ACT32 devices if board space is constrained. Verify that the 5V logic levels align with the system's input/output specifications before finalizing the design integration.

Part Context

This part belongs to the 54ACT series, which offers performance comparable to TTL but with CMOS power advantages. The 'Q' suffix indicates military-grade screening and radiation hardening. The 'WRQMLV' suffix denotes specific packaging and qualification standards required for defense and space applications.

Replacement Considerations

Direct equivalents include other QML-qualified variants of the 54ACT32. Standard commercial 54ACT32 parts lack radiation tolerance and extended temperature ratings. Verify pinout compatibility before substituting with non-QML versions.
