54ABT244W-QMLV

Overview

The 54ABT244W-QMLV is a radiation-hardened octal bus transceiver belonging to the ABT series, manufactured by National Semiconductor (now Texas Instruments). It features three-state outputs and is designed for high-speed digital applications requiring immunity to single-event effects. The device operates within a voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55 °C to +125 °C. It is qualified under QML-V standards and housed in hermetic packages suitable for aerospace environments.

Feature Summary

• Radiation hardness qualification ensuring reliability in space environments
• Immunity to single event latch-up and single event upset
• Hermetic packaging for extreme environmental conditions

Applications

• Aerospace systems requiring radiation tolerance
• Military electronic circuits
• High-reliability data bus interfaces

Procurement Notes

Verify that the specific part number suffix corresponds to the required QML-V certification level and hermetic package type. Confirm that the manufacturer documentation explicitly lists this variant as qualified for single-event effects immunity. Ensure compatibility with existing system voltage levels and thermal management requirements before procurement.

Selection Notes

Select this component when radiation hardness and hermetic sealing are mandatory. It is suitable for designs exceeding standard commercial temperature ranges. Verify that the ABT series speed characteristics meet the system timing requirements. Consider the availability of QML-V qualified versions versus standard commercial variants.

Part Context

This part belongs to the 54ABT series of high-speed CMOS logic functions. The series includes various gates, flip-flops, and bus interfaces designed for aerospace use. The 54ABT244 specifically provides octal buffering capabilities with three-state control, distinguishing it from unidirectional drivers or lower-speed AC/ACT series components.
