41138K

Overview

The IDT 41138K is a specialized integrated circuit component identified by the manufacturer as Dual Marked (5962-9223302MFA). This designation indicates compliance with military-grade specifications, specifically MIL-STD-883 Class B. The device is supplied in bulk packaging. As a dual-marked part, it corresponds to the commercial equivalent IDT 54FCT240T, which is an octal buffer/line driver designed for high-speed memory and address driving applications.

Feature Summary

• Dual marked to MIL-STD-883, Class B
• Corresponds to IDT 54FCT240T
• Octal buffer/line driver architecture

Applications

• Memory address drivers
• Clock drivers
• Bus-oriented transmitter/receiver circuits

Procurement Notes

Verify the specific revision level and lot traceability required for your application. Confirm that the dual marking (5962-9223302MFA) meets all necessary qualification standards for your system. Ensure the bulk packaging condition is suitable for your assembly process without additional handling requirements.

Selection Notes

Select this component when military-grade reliability and radiation hardness are required for bus driving tasks. It serves as the ruggedized alternative to the standard 74FCT240T or 54FCT240T series. Consider the package compatibility and thermal characteristics if replacing existing designs with the commercial variant.

Part Context

This part belongs to the FCT (Fast CMOS TTL Compatible) family of logic devices. The 5962- prefix denotes a Department of Defense microelectronics procurement code. The 'K' suffix typically refers to the ceramic flatpack package style common in military aerospace electronics.

Replacement Considerations

The commercial equivalent is IDT 54FCT240T or 74FCT240T. Verify pinout compatibility and ensure the operating temperature range of the replacement matches the -55°C to +125°C specification of the original.
