54ACTQ541W-QMLV

Overview

The 54ACTQ541W-QMLV is a radiation-hardened octal bus buffer featuring non-inverting, three-state outputs. It operates within a 4.5 V to 5.5 V supply voltage range and utilizes a 20-lead Ceramic Flat Pack (CFP) package. The device is QML-V qualified for aerospace applications, offering high total ionizing dose tolerance of 300 krad(Si) and single-event latch-up immunity up to 110 MeV.cm²/mg. It supports a military temperature range from -55 °C to +125 °C.

Feature Summary

Hermetically sealed ceramic flat pack construction
High radiation hardness against total ionizing dose and single event effects
Three-state output capability for bus driving

Applications

Aerospace satellite systems
Harsh environmental electronic circuits
Military communication equipment

Procurement Notes

Verify the specific QML-V qualification status and lot traceability documentation upon order confirmation. Ensure the procurement channel provides valid DLA or manufacturer certification records. Confirm that the component matches the exact 20-CFP package specification and lead finish requirements for your assembly process.

Selection Notes

Select this component when radiation tolerance and hermetic sealing are mandatory. It is suitable for designs requiring octal buffering with active control in high-radiation environments. Consider the 20-lead CFP footprint during PCB layout. Verify compatibility with 5 V logic levels and ensure thermal management meets the -55 °C to +125 °C operational range.

Part Context

This part belongs to the 54AC/54ACT series of radiation-hardened CMOS logic functions. These components are designed specifically for the aerospace industry to meet stringent reliability standards. The series includes various gates, flip-flops, and bus interfaces, all housed in ceramic packages to withstand extreme conditions.

Replacement Considerations

Direct replacements must be QML-V qualified octal buffers in 20-lead ceramic packages. Verify functional equivalence regarding pinout, voltage range, and radiation hardness specifications before substitution.
