54ACT241W-QMLV

Overview

The 54ACT241W-QMLV is a radiation-hardened octal bus transceiver belonging to the ACT series, manufactured by National Semiconductor. It features eight non-inverting buffers with three-state outputs and operates on a single 5-volt supply. The device supports asynchronous two-way communication between data buses via direction control inputs. It is designed for high-speed applications with low power consumption and latchup immunity. The component is qualified under QML-V standards and housed in a hermetic ceramic flatpack package suitable for extreme environments.

Feature Summary

• Radiation-hardened CMOS technology providing immunity to single event latch-up and upset
• Three-state outputs capable of directly driving bus lines
• Direction control functionality enabling bidirectional data transmission
• Hermetic packaging ensuring reliability in harsh conditions

Applications

• Aerospace data bus systems
• Military communication equipment
• High-reliability storage registers
• Pattern generators in space-constrained environments

Procurement Notes

Verify that the specific suffix indicates QML-V qualification status as required by the procurement specification. Confirm the package type matches the design requirements for hermetic sealing. Ensure the manufacturer source is validated against authorized distribution channels to guarantee authenticity and traceability for critical applications.

Selection Notes

Select this component when radiation hardness is mandatory for the application environment. The octal configuration provides efficient bus interfacing compared to single-bit alternatives. Consider the flatpack package geometry for board layout constraints. Verify voltage compatibility with the 5-volt logic family used in the target system architecture.

Part Context

This part belongs to the 54ACT family of high-speed CMOS logic functions designed for aerospace industry radiation requirements. It complements other bus interface devices like the UT54ACTS245 but offers specific QML-V certification. The series includes various gates, flip-flops, and multiplexers sharing similar radiation tolerance characteristics.

Replacement Considerations

Direct substitutes include other QML-V qualified octal bus transceivers from the same manufacturer or equivalent radiation-hardened parts from certified suppliers. Verify pinout compatibility and electrical specifications before substitution.
