54ACT241J-QMLV

Overview

The 54ACT241J-QMLV is a radiation-hardened octal buffer and line driver manufactured by National Semiconductor. It features non-inverting true outputs with three-state capability, allowing direct connection to bus lines. The device operates on a single 5-volt supply and is designed for high-speed, low-power consumption applications. It is available in a 20-lead ceramic dual in-line package (CDIP20) suitable for military and aerospace environments.

Feature Summary

• Radiation-hardened CMOS technology ensures reliability in harsh environments
• Three-state outputs provide direct drive capability for bus lines
• Latchup immune design enhances operational stability
• Single 5-volt supply operation simplifies power requirements

Applications

• Military communication systems requiring radiation tolerance
• Aerospace data bus interfaces
• High-reliability computing architectures
• Harsh environment signal buffering

Procurement Notes

Verify the QMLV suffix indicates Qualified Military Life certification. Confirm the CDIP20 ceramic package matches your board layout. Ensure the supplier provides traceability documentation required for defense contracts. Check for lead-free status if applicable, as some variants may contain lead.

Selection Notes

Select this component when radiation hardness is mandatory for an octal buffer application. Compare against standard commercial ACT series parts if environmental constraints are less severe. Consider the UT54ACTS241 if inverted outputs are required instead of true outputs. Verify pin compatibility with existing designs before substitution.

Part Context

This part belongs to the 54ACT family of high-speed CMOS logic devices. The 'QMLV' designation signifies qualification under specific military standards. It complements other radiation-hardened components like the UT54ACTS373 latch and UT54ACTS245 transceiver within the same product ecosystem.

Replacement Considerations

The UT54ACTS241 is a verified substitute offering identical functionality in a similar package. Both parts share the same octal buffer configuration and three-state output characteristics. Ensure voltage levels and timing parameters match your system requirements before swapping.
