54ACT175WRQMLV

Overview

The 54ACT175WRQMLV is a military-grade, quad D-type flip-flop with positive-edge triggering and three-state outputs. It features independent clear inputs for each flip-flop and is designed for high-speed digital applications requiring radiation tolerance. The device operates within a specified voltage range and supports wide temperature extremes typical of military specifications.

Feature Summary

• Quad D-type flip-flops with positive-edge clock triggering
• Three-state output drivers for bus-oriented systems
• Independent clear inputs for each flip-flop
• Radiation hardened design suitable for space environments

Applications

• Military aerospace data processing systems
• Spacecraft memory and register arrays
• High-reliability digital logic circuits
• Radiation-tolerant control systems

Procurement Notes

Verify that the specific suffix 'RQMLV' corresponds to the correct military qualification level and radiation hardness assurance requirements. Confirm that the manufacturer documentation explicitly lists this part as qualified for the intended environmental conditions. Ensure that the ordering information matches the exact package and lead finish specifications required for your assembly process.

Selection Notes

Select this component when radiation tolerance and military reliability are critical. Compare against standard commercial variants if environmental constraints allow. Verify compatibility with system voltage levels and timing requirements. Consider the availability of equivalent radiation-hardened parts from other suppliers if supply chain risks exist.

Part Context

This part belongs to the National Semiconductor ACT series, known for CMOS compatibility and high speed. The WRQMLV designation indicates a specific military and radiation-hardened variant. It is distinct from commercial versions by its enhanced testing and qualification standards for harsh environments.

Replacement Considerations

Direct replacements must be radiation-hardened quad D-flip-flops with three-state outputs. Check for equivalent parts from manufacturers like BAE Systems or Raytheon that offer similar MIL-PRF-38534 qualifications. Verify pinout and electrical characteristics match before substitution.
