54AC175JRQMLV

Overview

The 54AC175JRQMLV is a high-speed CMOS quad D-type flip-flop with clear, designed for military and aerospace applications. It features positive edge triggering and true outputs within a hermetic ceramic flatpack package. The device operates at frequencies up to 65 MHz and withstands total ionizing doses of 300 krad(Si). It is qualified under QML-V standards, ensuring reliability in harsh environments with radiation hardness against single event latch-up and upset.

Feature Summary

• Hermetically sealed ceramic construction for environmental protection
• High radiation hardness suitable for space missions
• Positive edge-triggered data storage with asynchronous clear
• Military temperature range operation capability

Applications

• Aerospace data processing systems
• Satellite communication interfaces
• Harsh environment control logic
• Radiation-hardened memory registers

Procurement Notes

Verify the specific suffix JRQMLV confirms QML-V qualification status directly with the manufacturer or authorized distributor. Ensure the order specifies the correct hermetic package variant. Request batch traceability certificates and radiation test reports if required by the procurement specification. Confirm lead times for military-grade components as they may differ from commercial equivalents.

Selection Notes

Select this component when radiation tolerance and long-term reliability are critical. It serves as a direct replacement for standard 54AC175 devices in non-radiation environments only if hermetic sealing is not required. Compare pin compatibility with existing PCB layouts. Consider thermal management requirements for ceramic packages in enclosed assemblies.

Part Context

This part belongs to the 54AC series of high-speed CMOS logic functions. The series is widely used in digital systems requiring fast switching speeds. The 54AC175 specifically provides four independent D-type flip-flops. The QML-V designation indicates it meets strict military quality levels for space and defense applications.

Replacement Considerations

Direct substitutes include other QML-V qualified 54AC175 variants from approved sources. Verify that alternative parts maintain the same hermetic package and radiation hardness ratings. Cross-reference with SN54AC175 equivalents if commercial grade is acceptable.
