54FCT244DM/B

Overview

The 54FCT244DM/B is a military-grade octal buffer and line driver manufactured by Rochester Electronics. It belongs to the FCT (Fast CMOS) logic family, providing non-inverting signal buffering with three-state outputs for bus-oriented systems. The device operates within a standard 5V supply voltage range and supports wide industrial or military temperature extremes depending on the specific MIL-PRF-38535 class qualification. It utilizes a 20-pin Small Outline Package (SOP) suitable for surface-mount applications requiring high-speed data transmission and isolation.

Feature Summary

• Provides eight independent non-inverting buffers with three-state output control for efficient bus management
• Manufactured under strict quality standards including ISO-9001 and AS9120 certifications
• Compatible with MIL-PRF-38535 Class Q or Class V specifications for high-reliability environments
• Features low static power consumption typical of Fast CMOS technology

Applications

• Military avionics data bus interfaces
• Spacecraft telemetry and command systems
• High-reliability industrial control networks
• Bus isolation in defense communication equipment

Procurement Notes

Verify the specific revision level and packaging suffix against the original manufacturer datasheet to ensure compatibility with your design requirements. Confirm that the MIL-PRF-38535 class designation matches your project's environmental and reliability mandates. Request full traceability documentation and lot history from the supplier to validate authenticity and manufacturing origin.

Selection Notes

Select this component when designing systems that require robust, high-speed buffering in harsh environments. Ensure the input voltage levels are compatible with the driving logic family. Verify that the package dimensions fit the available PCB real estate and that the thermal characteristics meet the system's dissipation needs without additional heatsinking.

Part Context

Rochester Electronics specializes in sustaining production for obsolete and hard-to-find semiconductors. This part is likely a recreation or surplus stock of an original component, tested to meet or exceed original specifications. It serves critical markets where long-term availability and reliability are paramount, such as aerospace and defense.

Replacement Considerations

Direct substitutes include other FCT-series octal buffers with three-state outputs from manufacturers like Texas Instruments or Renesas, provided pinouts and electrical characteristics match. Verify equivalent speed grades and output drive capabilities before substitution.
